I've been tinkering around with the idea of getting my family, just the 3 of us (son age 11) into table top rpgs.  A few weeks back I purchased Pathfinders Adventure Card game, thinking it would be a good starting place.  We all love it, so I just purchased the Pathfinders Beginners Box, along with the Core Rule Book.

So I have a few questions on where to go from here.

1. I have zero experience playing these types of games.  There's a local store that does a weekly D&D 4E, would going to this be helpful or make it more confusing? (as I realize they are 2 different styles of play)

2. Am I going to need more people to play/can only 2 of us play while 1 has to be the GM?

3. Can we create characters from the Core Rule Book (more options) and use them starting off with the Beginners Box campaign?
