If you want to sync your calendar or email then then information should sync automatically if your using Google. So for example you can use the HTC sync software that can sync information from calendars, contacts or your email to Microsoft Outlook. You can then use the Itunes application to sync your iPad. You can setup itunes to use Outlook and this way you can have synchronization between the two different devices.
If you use Google for your email, contacts and calendar then it should sync all of these without any complicated configuration.
