ArubaCare does indeed provide access to TAC via phone, email, or web. Whichever you prefer. It also gives users access to the software downloads section of the website; however, as a partner you will have access to that anyhow.
Are you in the US? If yes, talk to your Aruba Channel Account Manager. We have Channel Enablement Engineers that can help you with basic training. I put together a 1/2 hands-on course for IAP for the basics and another 1/2 day course for some advanced concepts. The Channel Enablement team can also get you some basic training on our controllers and switches as well.
You should also take a look at our training portal (Learning Management System (LMS)) at:

Courses start at basic and work up to advanced hands-on and can be taken at a training center or remotely. We also offer video based training for Instant and is a multi-part training series. This is found within the LMS after you register for access.
