The lines to get in on fan days will be ridiculously long - even for VIP - so get there early.
You have to be strategic when planning what stars you want photos with. You can be in line for up to an hour for the big names like Digital Playground contract girls, Belladonna, Bree Olson, Kristina Rose, etc. In that hour you could end up missing one of your favorite stars who is only signing at one of the smaller booths for an hour. It is practically impossible to get a photo or autograph from every performer at the show.
I do not think the parties hosted by the studios are worth it. If you go VIP you get the tickets for free anyway. I mean they are good to go to if all you want to do is go to a Vegas nightclub. However, do not expect to get anywhere near the performers, as they will be in a private roped off area. You will have a better chance to meet and talk casually with performers at the various bars around the Hard Rock Hotel.
I do not know if any performers are feature dancing as yet. Often you will not know until they start handing out flyers at the AEE itself. However, the main strip clubs will often have performers attend at some time over the weekend and that is an excellent opportunity to get photos with a star on your lap or even a lap dance. Perhaps check the various strip club websites. In the past Sapphire, De ja Vu, Hustler Club and Palomino have had porn star guests.
