I had the lift installed at a local shop that does a lot of work on Jeeps. I though about doing it myself but not decided I had more money then ability and didn't want to mess this up. My shop put on the lift and did my tires as well. They also took it to a shop and had the whole thing aligned as part of the install. The lift and install was only $1050.00 plus the tire and wheels. No, I don't see any issues at all with a 3" and 35s, you will have plenty of room.
