For bags, the OEM equipment only allow for either the top rack or the side racks...not both.
I can't provide detailed help on racks for the 2010+ bikes, but I'm sure others will offer great advice. And the search function will be your friend...there is a lot of great information on this site.
In general, a number of manufacturers offer aftermarket racks, with SW-Motech,, Givi, and Hepco-Becker being the most well known. Happy-Trail.com also offer side racks if you like using Pelican cases or aluminum panniers. In some cases, they allow top and side cases to be used (Givi). In others, they may not (SW-Motech, according to Twisted Throttle's website).
As for vendors, I'm a proponent of shopping locally, simply because if local dealers do not sell merchandise, they tend to close. That helps no one. If you want to buy online, check the vendor section of the site. As well, other dealers are Twisted Throttle
Have fun, and enjoy the bike!
