New FX4 Owner!

so now that I have her its time to lift her. I'm getting a 2.5" leveling kit from Rough Country and 35x12.50R17 Dick Cepek FC II. I want my tires to stick out some. I want a nice black rim for the truck but dont know the proper wheel backspace or offset.
Here are a few things I'm considering purchasing in the future and would like to know your input
Cold Air intake
Whats a nice muffler that isnt annoying on highway but when you floor the accelorator sounds loud
Programmer?
Upgraded stereo, like a touch screen? stock one isnt cutting it
Sounds pretty mall crawler lol but I have my 92 to do my dirty work
