Interior stuff.
 

Where is a good place to get some good interior stuff like shift knobs, shift boots, gauges, pedals etc? [???:)]

Probably the cheapest place is the local junkyard, and you could check out the for sale section of the forum.

Check out Redline Tuning for floor mats, Redline Goods for shift boots (names are coincidental), Steeda for shift knobs and HVAC knobs, Metal Monkey for gauges (UK company, not cheap), Rickbrook for knobs and boots (another UK company), and our How-To section here for cool ideas and tricks.
