I know exactly how you are feeling. I was totally overwhelmed in the beginning. Still am sometimes! Now I have somewhat of a plan, if you can call it that. I like to scan the forums for interesting threads where I can learn something, help someone else out, or both. A couple of times a week (wish it were more, but there's that pesky problem of delivering a product to clients!) I glance at article topics because there are great ideas there, too. I'm not able to make it to as many of the events, but I usually check once a week to see what's being offered.
I'm sure you will find your own rhythm, based on what's most important to you.
As far as paid memberships go, check out this chart. It's a great, visual way to compare the benefits that come with each level.
