Hey Rocky, welcome, it is a pretty easy game to pick up and this site has been a great place to learn. Everyone is really nice and willing to help, so if you need any questions answered, don't be scared to ask.
For your messages, I'll answer them here.
Pretty much any character you want. You can use one of the three common point systems
1: Roll 4d6, six times, dropping the lowest number (so if you roll 3,4,6,2 you would drop the 2 and the stat would be 13)
2: The standard array, 15, 14, 13, 12, 10, 8 put where ever
3: point buy system you have 27 points to spend

This is my first game that I'm GM'ing so backstory isn't a necessity, the religions and gods are just the standard D&D ones. You can find a long list
here or if you already have one in mind feel free to use it.
