If you don't have a 64-bit operating system, either XP or Vista the OS can't take advantage of the 4GB of memory.
If your CrackBerry is from Verizon (or possibly other carriers) using it as a tethered modem would be cheaper than a mobile card in the notebook.
I've got a 17" screen on my HP but I think that for most people a 15.4" would work better. However on this size screen you don't usually get a number pad.
Almost all notebooks have some way to dock, either through a docking port or a universal dock through the USB port.
