Welcome to the forum. There are lots of great ideas all over the forum. Just a suggestion... Take the time to search and read. You'll find answers a lot faster than waiting for people to answer you.
BFG KO2's, depending on what lift and size tire you get will determine the rim size ie. width and offset. bilstein or Old man emu make good suspension lift kits for reasonable prices. If you're going to be wheeling the truck at all I'd stay away from a leveling kit they are typically spacers in front and blocks in back. Light bar locations depend on the look you want what size bar and the mounting bracket points.
