Welcome to the forum! In my opinion, the Bill Lawrence L-500XL is the ultimate lead pickup, but the clean tone isn't all that great. You can install a sustainiac in a humbucker space, alongside a single coil, or mini-humbucker. As for the wiring, if you are going to install the sustainiac, you're going to need some wiring knowledge, but if you were to just replace the pickups, all you would need is a soldering gun, solder, and a wire code for each pickup. Very easy stuff. I know that www.musiciansfriend.cm sells pickups, and www.billlawrence.com sells the L-500XL. Good luck!
