Swapping dash lights on 01-04

I want to change the lights on my dash cluster and my ac lights and possibly the overhead lights. I hear they are a pain. Is there a thread with a walk through instructions??? I don't want to get half way in and then be stuck. Also I want to know exactly what light to buy??

 

I have never seen a good instructional on which lights to buy exactly. I think a few are 194s or t10 and the rest are something else. There are main bulbs and smaller ones. The inst. panel is not hard to take out though. Many are putting them in 2nd gens here, but that is a different process.
