new in town

I just got my Motorola Droid early this week and trying to find time to figure it out. I selected this model based on my needs, reviews, and price point. Left behind my Blackberry of two years, felt somewhat limited, and wanted to stay with Verizon.
I have an online business and want to be able to utilize it more while on the go. Is there a general sight that would initially would help me navigate this phone?
Secondly, are there apps on the phone that most consider useless and should be removed? In reading reviews I saw that several people mentioned ones that can really suck your battery juices. Any suggestions?dancedroid

 

It's hot here now. Transferring info from blackberry

The heat is upon us now, but we had a great, extended spring, so can't complain.
I don't need to worry about credit cards, and might use GPS once in awhile. I did find my way to "manage applications" and did find that I had some running that should have been turned off, so got that.
So, how do I go about transferring contacts, etc from my blackberry.

And I am such a newbie that I don't even know what 'rooting' is. Is that the same as connecting to my computer?

 

I just heard about speedtest.net yesterday. Interesting.
