Store and Membership options?

What plugins are available and recommended for an online store and to which gateways do they connect? (Paypal, e.g.? )

Also, we use a membership model that automates monthly and/or annual subscriptions for vendors and users. This is automated in vBulletin. Is this a standard feature in XF?

Finally, is there a Matrix of included features and plugins? Or a comparison chart to vBulletin? (even if done by a third party?)

Sorry if these questions seem obvious, but working in the admin in the demo for a day or so doesn't really help me figure out all we need to know because the learning curve is rather steep. The program seems easier than vB, but knowing all features and capabilities isn't.
