I've recently become slightly obsessed with trying to figure out what I want to put on my pearl

From what I understand the pearl has less memory than the other phones so I dont want to overload it, how much can I put on it (safely?)
So far I've put weatherdirect and googlemaps
I want to / thinking about adding google reader, google search, yahoo go, jiveslide, ramble, and the list application from Maratick and maybeee BBtoday
About googlemaps- assuming I have this program, I can probably get rid of blackberry maps correct? And when I got the phone Verizon told me it would be 10 dollars a month to have the gps- was this just for their vz navigator (ie, will my gps work with googlemaps without paying verizon an extra 10 a month?)
Ive taken brickbreaker and password keeper off my phone already to save space, and I have a memory card for my pics.
also I've seen people talk about opera mini a lot and I am wondering exactly what the perks are? I tried to search it on the forum (I mostly found problems people were having, not a description) and I went to their website but I dont see how it differs from the blackberry browser, if I dont have wifi on my phone...
thanks guys!
