Welcome! There are lots of threads on lifts. I'd recommend doing some research, narrow it down, and then fire off some more specific questions. Cant' really recommend anything, especially without knowing what Jeep you have.
10.5" width wold be a 265 series tire. That's easy to find in 31" height, might be harder in 37. Tires are getting HUGE these days.
My first suggestion? Get the catalogs and leaf through them. I always dog-ear the pages of things I really want. Quadratec, JCW and 4wd all have good ones. You can buy them at a newsstand or get them free, if you're patient.
