Oh, if you do decide to buy this bundle, please use my referral link: http://www.macheist.com/bundle/u/150924/ (I don't really need Pop-pop, but the Koingo Utility Package sounds interesting.)
The really nifty things that I definitely have a use for:
World of Goo (although I already own it)
WireTap Studio (Had owned a pirated version, for the few times I need to record audio from an application. Now I have a real license. Woohoo!)
Really expensive stuff that I'll probably never get around to using:
Kinemac ($299) - 3D animation studio
BoinxTV ($199) - TV studio software
Expresso ($80) - Web development editor.
