Some basic info:
Ibanez RG's come with 9-42 D'Addario strings. If you replace the strings with a lighter or heavier set, the bridge becomes unbalanced rather than returning to it's neutral pitch. The reason why is because of the change in string tension which is countered by the tremolo springs.
If the bridge moves forwards (because you fitted heavier strings), you need to unscrew the plate on the back of the guitar and adjust the spring claw screws. Tighten them just a little bit, retune the guitar and make any further adjustments as necessary. The screws should be parallel, btw. I've seen lots of pics of trem cavities where people had the claw angled. This sucks!
If the bridge is angled back (because you fitted lighter gauge strings), then the spring claw screws should be adjusted. Unscrew them (anti-clockwise) a small amount, retune the guitar, and repeat until the bridge is balanced.
It's fine to remove all the strings at once, contrary to what many people say. Removing the whole set is the only way to get to the fretboard when it needs cleaning or if the frets need polishing (with steel wool). I clean the board all the time, partly because I'm scared of the maple on the RG20th becoming dirty and worn, and partly because a clean guitar feels so much better to play. Rosewood and ebony boards also need a good dose of Fret Doctor
Rich Harris has some good information on his website. Newcomers to Ibanez and / or guitar maintenance in general should read it. I know a fair amount about setting up and taking care of guitars, but I definitely learned some stuff from Rich. See here

They don't go through the machine head completely, the ball-end snugs right up to the tuner peg.
