The link definitely works. I think that you would probably benefit a lot from scale studies and private tutoring. I personally don't know how you got through the first year of playing without going through at least the basics of chord theory and basic scales. You would also benefit from a metronome. You can usually get one pretty cheap.

The setup I use for practice is a Digitech RP200 going through my sound card in my computer. The RP200 has a built in metronome and tuner along with a whole slew of cool effects. I would also be using protools free version to record with if I wasn't running windows XP. I use Cakewalk Pro Audio 9 to record with. You might want to try the free version of Pro tools to record with instead of the microphone on your computer. You can get a much better sound. You also can get amp farm for pro tools which would make it as easy as plugging into your sound card and having a warehouse full of amps to play with...
I'm getting too far off track... First find a teacher. I have played for 20+ years and I made my biggest gains by searching out tutorilage. Make sure you get the best teacher for your money. Don't just take the first one you come across.
