The bonus for UPC III is +3 (facility.txt), but I believe it is in percentage rather than in tenths of percentage, which would make +30 in the happiness file. At least, it should be something along these lines as you wouldn't otherwise be able to offset the natural decrease of 20 per turn.

A lot of troops would work here to solve the matter, but the hit to colonizing planets does hurt. However, it seems like you do not suffer if your planets are being glassed, so that would help a *lot* if you are under attack. You will take the regular happiness hit if your planets are being captured though.
