I try to pick songs that are pretty much standards at jams - though I get off track. Don't be intimidated by others playing. Even if you can just one button it, get the song out there. That's a huge leap to make and sets a bar for yourself to push up. Listening to songs I recorded and posted a few years ago gives a sense of accomplishment for what I'm doing now.
Tabs really aren't a good way to go about it. You get to depend on them when you just need to learn what buttons to mash to make the sounds you want.
If you don't have internet at home, then it can be difficult if you are far from the music scene. The only way I get by is to download videos, slow them way down and watch what they hit.
Get the various instructional videos and work on them. Listen to the songs and hunt around for the sounds. Get a metronome and work on the basics over and over. You will be surprised at how, once you relax into the metronome work, you will start to just pick stuff up. Play at least a little every day.
