I have installed iDeneb 1.4

I'm not going to bother with the upgrade kit as my system is stable and working i'm happy with that. (how safe is it actually? 10.5.6 to 10.5.7)

When i click Software Update it wants to download an update for the following apps:

Logic Pro - this is not legal version
iLife Support
Airport Client Update
Front Row Update
Quicktime
iTunes
MAC OSX Update

So my question is, i know i cant run MAC OSX Update, but can i run the app updates, foritunes, quicktime, frontrow, logic etc...?

Logic is not legit, so will running that update lock it out?

Thanks
