I've used the AAW kits and like them.
Tips,.. read the directions thoroughly, and also get the correct crimping tools. I like to solder the wires to the terminals too, but that's not really necessary, as long as you have a good, solid crimp. Get the non-adhesive wire loom tape if you're going for a factory type of appearance. Regular black tape doesn't work as well, especially when moving the bundle around corners, etc. The non-adhesive tape lets the bundle move around and seems to work good. Also, saves you the sticky mess down the road when working on it for whatever reason.
As far as the dome light wires, I re-use the existing wires for that. As long as the originals are in good shape, I don't like fooling with the headliner unless absolutely necessary.
If not concerned about the factory look, or for added protection in friction areas, I really like the split loom type in the link below (Holley uses the same type loom on their EFI harnesses, FWIW). I keep most of the sizes in stock here at the shop. Also have the asphalt coated stuff in stock, like the factory used around the starter area, etc.
