Re: Does Ibanez neck removal require truss rod adjustment?
Here is how I would do it.
First of all, I don't believe it's necissary to take all the strings off individually if you are doing a quick tweak (like adding a shim), but since you are doing it for a while, you can. However, I would start by taking the trem out, with the strings attached. Start with the outer 2 springs, then the middle one, while supporting the trem, because of the force of the strings. There is a longer tutorial on this at ibanez rules. The you could use your allen wrench to loosen the string locks so the strings come out of the trem. now with the strings limp and removed from the trem, and the trem removed, you can take the neck screws off. Make sure the guitar is sitting flat with the body and neck being supported, the neck is actually heaver then the body, contrary to belief! I would also make note of which screw goes where, I believe the front and back ones are different lengths as well.
Now to answer your real question. No, It should be fine as long as when you go back you are using the same kind of strings in the same gauge. it make take a day or two for the strings and neck to settle back in right, and during that period I would actually leave the locking pad of the nut off, since you will be constantly tuning.
Maybe rich can chime in.
