Ok, underglow first; neon or LED?
(I have both.)
Neon: I personally think it looks better with a nicer more even glow.
Drawbacks: its only one color, has no patterns, and is much more prone to breakage.
If you choose neon Pilot has a set that’s hella bright.
One of our club members has it in green:
Blurry, but here you can see his ride compared to average neon sets:
LED: Most folks will tell you this is better. I just have a cheap Pepboys special myself. If you’re on a budget it works.
If you’re going higher end here are some features to look for: how many different patterns, color combos, ability to respond to music, can gang multiple components together (ie tire wells & interior), and a remote control. I’ve heard good things about varad (
http://www.varad.com/v4/) and the FlowLighting Inferno from Oznium.com. I’m sure there are plenty of other good options out there & folks who have them will chime in soon.
Dome light: switch to LED & forget the crap at Pepboys.

Interior:
I don’t use them myself, but I’ve heard a number of folks use cold cathodes made for CPUs to light their footwells. If you search around the threads you should find more info.
(I just don’t recommend using them in the handholds in the roof. I keep picturing someone grabbing them and coming away with a handful of broken glass.)
Again I’m a real fan of Oznium especially their prewired LEDs. Used with bezels the 3 & 5mm LEDs can be fairly discreet in cupholders, handles, the glovebox -- all those little spots. For a bigger bang try their prewired superflux 4-chip. (I actually use these in my headlights shown blue above.) I also just ordered their new chrome LED modules. They’re bright & not bad to look at either.
Also, here’s some DIYs to check:
