Shame you're not in the US, Ben. I could sell you muy Charvel/Jackson electric, shielded cables, D'Addario strings and Crate 30watt amp.
Steve Vai was supposed to have come out with a some kind of "Teach Yourself Guitar" software. I also know there is other kind of guitar instructional software for the computer, but can't vouch for how good it is. If you can find a review from Guitar World magazine on any software, it will likely be very comprehensive and give you a better idea of it would give you the level of detailed instruction you need.
In the US, they've really been pushing this "Esteban" and his guitar instructional package and video. They don't offer much detail on the informercials, and none of their 'students' even play in their demonstrations (they don't have their hands forming simple chords, don't even really strum properly either--it's quite fake). LOL
