A few questions before making the switch

[GRB]

Hi Ya'll,
I've been on a WinMo phone with Sprint for the past few years. I'm fixin to make the switch to a droid phone since Sprint isn't currently offering a top end phone w/o a keyboard.
Here's a few questions I'd like to have answered before commiting:

1. Will it sync contacts, calendar, and tasks with Thunderbird (Firefox/Mozilla)?
I have T-bird on my PC and I'm happy with it. I don't really want to switch to gmail, since it's website based. I currently use Birdiesync on my WinMo phone to do the syncing.

2. This is prolly a dumb question, but are the Android phones capable of running multiple apps at the same time?
