God damn... this minor pentatonic scale is kicking my ass.
MrStitch, if all this scale talk seems a little overwhelming, just focus most of your attention on that first position.
Seriously, you can get a ton of guitar solo mileage out of that first position of a scale. After a while, you will get bored with that-- and you should. If every solo you write never strays from that first position, you will sound one dimensional. So, I'm not saying "ignore" the other positions. The other positions give you different flavors of the same notes.
When I'm improvising, or just messing around trying to get a feel for what I want to do with a guitar solo, I almost always start with that first position.
Also, I think good old pen and paper really helps when you are learning this stuff. If you aren't sure about what key a song is in, write down the chords on paper (E, A, B, etc.) and then write down different keys:
"Hmm, I think this might be Emin (a good starting point if you are playing metal), let's see Emin is: E F# G A B C D. Looks like that E A B chord progression might be in the key of Emin."
Hell, now you are half-way there! Bust out that first position pentatonic minor scale, start on the 12th fret, and play what you feel.
The other tough thing to work out is playing a scale without sounding like you are playing a scale. Throw in lots of bends, hammer-ons, pull-offs, slides, and skip notes. That stuff will keep it sounding interesting.
