I got my "new" MBP today, and so far I love it

I have some questions though. I notice there is some trial software preinstalled (Aperture 1.0, Word for Mac 4.0, etc.), that I'd like to remove. Is it just as simple as dragging the icon to the trashcan, or is it a bit more involved?
Also, I have Mail set up to check my Gmail account which is configured for POP access... for some reason though, I'm having trouble sending mail through the SMTP server - the same is true for the .mac SMTP server as well so I'm thinking that there is something configured wrong on my end. I just ran the automatic configuration.
I'm sure I'll have more as I've been using PCs for YEARS
edit: Never mind on the mail problem, I just changed to the alternate port #
