Hi and welcome!!
There are some threads for "must haves" all over, top 10 free and things like that. IMO kind of depends what your after, I would just suggest not to load a bunch at once just cause its hard to find that "one thing" thats messing something up.
I like to watch this thread: Storm 3rd Party Apps - BlackBerry Forums at CrackBerry.com
Many apps (most) seam to hit there pretty quick.
