Would the Moon (which has some gravity) or a large space station between Earth and Moon or in lunar orbit be a better 1st step for the 21st century? Earth spacecraft could then refuel and provision there for the long haul all the way to Mars. Earth base Mars being for the 22nd century?

Getting a craft with humans to Mars is not a problem. It’s getting enough resources there too to sustain them indefinitely.
It is incredibly expensive ( 1/4 million $) to move 1 kg of equipment from her to Mars.

Speaking of practicality: what exactly would be the point of a "human base" up in outer space? The ISS is useless enough, so what would be the point of having fragile humans with all their cumbersome life support systems holed up on another planet? What would it actually DO for you? What would it DO for me? What use would it be for anyone?
Funny but once you puff away the clouds of hype that surround the notion of humans on Mars, there is no substance. Nobody discusses what we do with it, what use it would be, and how the colossal cost would be justified. All you hear is airy fairy ways to go about it and the corny old cliche: "oh Mars is the stepping stone to the next planet". Lol, it begins to look like a cosmic Ponzi scheme. Fund up a Mars base, then based on the sheer hype, seek funding to the next planet, then more hype, and fund to the next. At what point does the public realise the pointlessness of it all?
If we truly want to explore the planets, moons, asteroids and comets in the solar system, the tried and proven way to do it is robotically. It costs less than one percent of cumbersome and troublesome manned missions, is far more reliable, and just as effective if not more so.

A one way trip could be as short as 6 months
Bigger problems are the lack of sufficient gravity, lack of breathable athmosphere, and lack of magnetic field to protect from all kinds of radiation
?
I think it has possibilities, if someone could come up with the Money
Now Yahoo Answers is ending, I would go myself
Because there is Bugger all else down here

1) Is Mars too far for a practicable human base this century....?
No...not if a nation
or a consortium of nations
has the will and finances to accomplish it.
A permanent base is certainly possible.
It would be VERY EXPENSIVE to establish.
It might NOT be outrageously expensive to maintain, especially if something like the Red Dragon becomes a "standard transport vehicle" (for both humans and supplies) to and from Mars.
Once established
the base ought to have an "escape / return to Earth" vehicle always "ready" in case of emergency.
- TWO such vehicles, eventually
We could ship supplies to Mars on automated transports
and
we could replace the crew of the base at regular intervals.
(I.e. much as we do now with the ISS, except the intervals would be more like 18 months.)
2) Would the Moon (which has some gravity) or a large space station between Earth and Moon or in lunar orbit be a better 1st step for the 21st century?
It would certainly be EASIER
and CHEAPER
and
thus
MORE ACHIEVABLE.
One could establish "transfer stations" (space stations) orbiting both Earth and the Moon
and so
- standardized transport between Earth and Earth-transfer-station
- standardized transport (different type of vehicle) running between Earth-transfer-station and Moon-transfer-station
- standardized transport (different type of vehicle) between Moon-transfer-station and Moon
Basic reliability testing could be done at the transfer stations to make sure that the vehicles were still in good operating condition. Vehicles could be refueled at the transfer stations.
Note that you would need not only people transport, but also allow for supplies transport and safe fuel transport, for this system to be worth the expense. It would also be nice if the system supported heavy equipment transport (so that you could get large items to the Moon without having to use a direct Earth-to-Moon system).
3) Earth spacecraft could then refuel and provision there for the long haul all the way to Mars. Earth base Mars being for the 22nd century?
The (potential) problem with a space-based Mars flight is that it's not particularly easy to work on (evaluate, transfer supplies, etc.) spacecraft in space. I mean: you'd STILL have to get the Earth-to-Mars spacecraft in orbit...and the fuel... and the people...and the supplies...and load all of those things ON the spacecraft, and generally that's going to be easier to do ***from the ground*** than it is from space. (I.e. easier to put all of those things in your Mars-bound spacecraft on Earth than it would be to transfer all of those things to your Mars-bound spacecraft in space).
But if you have ***reusable craft*** running a ***regular route*** and requiring minimal maintenance
- or, if the craft is small enough, ***a repair bay that can be "aired up" so that the craft can be serviced in space***
then you have an economical solution
because the operating costs will be RELATIVELY small
compared to a from-Earth-ground-to-destination-and-back-all-in-one-package solution.
