What kind of electric guitar pickups are best for me?
The second paragraph is my question, the first will be the situation; you can disregard the first half of this question if you don't need that much information.
I've played guitar a little over a year. Though I'm by no means great, I plan on starting lessons in the next few weeks (I've learned everything from time signatures to vibratos to scales to chords to hammer-ons/pull-offs, the circle of fifths, even a few licks on my own). I hope my lessons will take me a little higher in my guitar as I'd like to perform in front of family and friends before 2015. I have 5 guitars; 1 acoustic, 1 acoustic-electric, and 3 electrics. All my guitars have been used and bought rather cheaply, and I have taken them to stores for repairs and putting together some different things. There is a used guitar I would like to get soon, it's a Warbeast electric. Being concerned about spending a few hundred dollars online, I have taken the liberty of reading some reviews on the guitar. Most of which are positive, but have honest feedback about the pickups being terrible, and the headstock being a little weighted, making it no good to play sitting down. I plan on having the guitar shipped to Guitar Center and picking it up there.
Since the pickups are no good on the guitar I am buying, I would like to get pickups for the guitar that will, more or less, be my type. I enjoy a more thrash metal type of sound (my favorite band is Anthrax), but I want a little bit of versatility--not a lot, mind you, but just enough to where I can play it without distortion as well as with a pedal or two. I've never purchased pickups, nor do I know the first thing about them. I want to be able to play some really speedy licks, but also be able to tone down to, say, a nice slow opening like Metallica's "Welcome Home (Sanitarium)". What kind of pickups should I look for?
I will call ahead to a local guitar shop to get the pickups and some new strings put on the guitar the first day of having it, so I'm not too worried about price as long as it's between $1 - $200, I have time to save up and get the right option. What would you recommend?
PS. I would also like to change tunings on my guitar for things like "Walk" by Pantera (Drop D), though I will not go lower than a whole step down on all strings (DGCFAF)

EDIT: Yes, I need to get the really good ones. But what pickups ARE really good for thrash metal type of music?
EDIT: Guitar is $500. All my other guitars are actually pretty nice, They've just been used (all of them are $300 or more brand new, but I saved about $50 by just buying them off friends and hooking them up with some new strings and a new nutstock etc.) I just want to add a Warbeast for design and to have some fun. It's not a bad guitar, just that it's not an extravagant $2000 one. I'm getting a $1300 Floyd Rose with a whammy soon. That's why I said I'd pay up to 200 in pick-ups. Because some nice pickups in a semi-nice guitar would be awesome to me.
EDIT: It says it's got 2 humbuckers, though I'm not exactly sure what those mean. I appreciate the help, I really do, I hope I don't come across as a bit of an ***, I've just been looking at the guitar and customer reviews are all very positive but mention that the pickups are a bit muddy and that the headstock is weighted (which isn't surprising because the guitar is a Warbeast so it has one of the ridiculously huge headstocks)
EDIT: Cnewshadow: 1) No, I'm not fluent in specifics of guitars, which is why I'm asking about different things first.
2) I'm bothering with this one because I'm not great with adjusting the tension of the bridge on a Floyd Rose. Yes, I know, the brand is not Floyd Rose, I've had one before, almost bought a second one and changed my mind because I was going to wait until I was better with swapping the strings on it. It's a Synyster Gates signature Schecter guitar, brand new could be upwards of $1300, I'm sure if you looked around you could get it for about $700 used, which is still more than I'm paying for it (friend likes drop tunings, was not smart when he bought the guitar for $1300, he wants to get rid of it and nobody wants to pay $500 for it).
3) I'm not dead set on the Warbeast, mainly because there's a few Explorer guitars I've been wanting, but I am still seriously considering the Warbeast simply because it'll be nice to have it,
