Although ive leveled these to 80, ive never multiboxed on them, neither have I ever tried PVP.

like they said before multiboxing draws a lot more negative attention than solo leveling. its really up to you but you can level all 4 again after the ban or one more before it.

as for your other questions... software is personal preference check out the wiki and decide for yourself.

i believe you play them and gear them pretty much as you would a normal solo toon. heres a link to a fairly successful elemental shammy in 5's. i dont know if its exactly what you would want but its a good starting point.

and lastly i cant imagine there would be very many spell rotations in pvp. aside from some burst combos it seems more like you just have to practice and get used to what spells you need to use in certain situations. i would suggest lurking some pvp sites and forums as well as this sites pvp forum. the pvp section of the wiki here seems to be lacking in content but you should be able to find some good info in the forums. you just have to do some research.
