I'd like to know how to form sweeping/other arpeggios, like what are the keys like how to form a minor7 etc. no need to tell em all, just the basics like how to form a minor arpeggio etc.

A basic arpeggio takes a given scale, and uses the root, 3rd, and 5th degree of that scale.

Say you have A Natural Minor
A, B, C, D, E, F, G, A
root=A, third is C, fifth is E

Then figure out where you can put that on the guitar:
E|-----12-17-12----
B|---13--------13--
G|-14------------14
D|-----------------
A|-----------------
E|-----------------


And there you have an A Minor Arpeggio. You could also look at it as a chord. If you take an A minor Chord, you have the notes A, C, and E--then just figure out a way to play them one by one. The same works with any scale or chord. A few other simple ones you should try would be Major, diminished, 7, Major7, Minor 7, diminished 7, and augmented

Simple. Learn the basics of chord construction and you'll be able to do it yourself. Use the theory sticky in the MT forum.
