For the contacts I had to save all of my contacts to a CSV file and then import them into google. For the Calendar only you could try and use the google calendar sync program that they have. On their site they have strict requirements on what it works with though. I have Windows 7 Professional and Microsoft Outlook 2007 and it works great. I still primarily use Outlook for my calendar and then go into gmail for my contact management.

These forums seem like they are a lot quieter than most because of the aggressive moderators getting rid of generalized android questions and moving them to the appropriate forums that they belong to. Otherwise the specific phone forums are just for that, the specific phone that they have. Due to the same Android system running on multiple phones with their respective manufacturer tweaks there may not be many phone specific questions.
