It seems I may be exploring video editing sooner than later.
While my skill level with video would certainly classify me as a novice, I like to invest in tools which allow me to grow. I know about Final Cut, Premier, After Effect, etc.
I am considering upgrading from one of Adobe's Premium Suites to the Master Collection to get these tools. That seems like a natural progression. But I want to ensure it's one of the better directions to follow. After all, if Final Cut is better, why bother with Adobe. Or even if both the Master Collection AND FinalCut have benefit I'm willing to go that route as well.
For the most part I'll simply be resizing, cropping, and compressing existing files to start. Eventually I will move into clipping and inserting titles, splashes, etc. I'm well versed with Photoshop and Illustrator and can easily use those as support software provided the video software will allow the integration.
I'm currently using a wide variety of the smaller shareware or freeware apps such as VisualHub (discontinued) and Handbrake along with QuickTime Pro. Also rendering via Photoshop Extended to some degree. I tried iMovie a couple times but it was far too limited in many cases and I wasn't attempting anything I'd call "advanced".
I'm assuming any high-end editing package can produce compressed .mp4 or mpeg2 files much better. And from there I can easily deal with the Adobe Media Encoder to convert for Flash/HTML5 use if needed. I'm primarily interested in using recorded footage to create digital assets which could then be multi-purposed for various physical or digital delivery.
Running Mac OS
So I'm looking for any recommendations from experience video designers on what software helps them get their job done faster/easier. It's not so much about cost as it is about product reliability and functionality.

If there are any third-party plug ins or add-ons which you find you simply "can't live without" for video editing, please share those as well.
