I use Citadel's super glue - whatever it is.
I've used regular superglue in the past, as well - and for particularly large miniatures, I'll occaisonally use something like JB weld or an epoxy.
For paints, I use a mix of Citadel/Warhammer paints and Reaper's Pro-Paints. I find that if they're well cared for, they both can last a number of years. For the most part, I like Citadel paints better, but there are a few great Reaper paints (their maroon, for instance, is infinitely better than either "scab" or "gore" red).
