1. How much money do you want to spend? You can piece the stuff together, or buy some kits. Front only, or rear steer too? Rear steer brings in alot of other concerns, volume, heat, pump capacity. Huge thread on pirate - search "koh steering"
2. Look at Speedway Motors, Day Motorsports, Jegs and Summit and start searching. THey all have mostly the same, but a little different stuff. I like the fine splined adapters, but the hex adapters have worked for a long time.
3. How big is the buggy? Are you going to be using it for axle suckdown or just recovery? How heavy is the buggy? IF Your buggy is light, consider the competition winch or a m6000 sdp. If it is a heavy mofo, you may need to consider the 12,000. Are you mounting it to the axle or the body? the sdp and competition winches are lighter and do a little better mounted to the axle. an 8247 is still a badass winch, but hard to mount with its height
4. All fuel cells are pretty safe, but there are alot of options. Aluminum or poly? How big? Foam filled or not? In tank pump or not? Do you need a sending unit??
There are a million different ways to do all of this stuff.
Alot of searching and reading will do you well.
First decide exactly what you want, then start shopping for it.
