Help JB not installing correctly

[Vigi1ante]

I have been lurking for about a year now and until now I found out pretty much everything I wanted or needed to know from searching.

Well long story short, I uninstalled "important" apps and now I get a message saying the update failed. I was wondering what the next step is now? Can I just download those apps and then it magically works? Or would it just be easier to reload a stock ICS ROM?

Thanks in advance!
