The max psi on the tire is related to the tires construction and their load carrying capacity. The 35 psi recommended by your vehicles manufacturer takes into consideration your vehicle weight and design, go with what your vehicle manufacturer recommends, 35 psi.

You can run the tires below 35 if you wanted to. But this would cause the tires to wear quite fast, cost you fuel efficieny, and possibly cause a blow out.
You could also pump the PSI up higher if you wanted, this will improve your fuel economy a bit, but the higher pressure would make the tires less grippy and the suspension of the vehicle would not be optimal.
Best thing, look for the PSI sticker on your vehicle. Most vehicles it will be on the inside of the door jam of usually the drivers door. But check all 4. Or if you still have the owners manual check it. It will say what the vehicle's recomended PSI is.
This PSI is what the engineers designed the suspension around and will be safe with any tire you put on the vehicle.

No real life drawbacks Ride may be slightly stiffer up front for a 40 series tire. Speedometer will be off by a very minor percent, but not enough to notice or get a ticket unless you're going over 100mph or so.

keep the tire pressures as equal as possible. also as long as the tire sizes are the same you should have no problems.

no. just make sure the tire pressure is the same in all of them so you get good gas mileage.
