Droid contacts & scheduler options

Hi- finally moving to a "smartphone", but want to make sure it is integrated with my existing technology.... The main thing is the contact manager/calendar. I use Palm and Thunderbird now. I don't care about keeping palm, but I like Thunderbird for security and its non-commercial non-intrusiveness. I'm trying to find out what my options are, without patching together a bunch of apps...

Any suggestions?
