I would do the same thing as far as syncing goes. I also once owned an E71, I loved the hardware on those phones but not the OS... I'd get acquainted in general with Android for a bit, check out the market, and go from there. Few helpful tips:
-holding down the home button brings up task manager
-the option key (far left) is useful in a lot of situations. If you're stuck in an app but want to change it's settings or don't see the button you need, try hitting option!
-set up gmail and Facebook if you'd like to have sync'd contacts including contact photos
-if you use dropbox, go grab the app from the market!
-if you tap the home button and the lock button at the same time, it will take a screenshot. The screenshot can be found in the gallery under that name (screenshots), if you open it in there and tap on the image, more options will appear below so you can share the image with us for example if you need help with something.
