The JazzN is a low output PU & would cause less feedback than most other HB's. No cause for concern there.
I've rewired several dozen F hole guitars (335's & full hollowbodies, including a couple of Ibanez). I've put the 4 push-pull Jimmy Page system is a few of them. It's not hard at all, in spite of any stories you may have heard. I knew an otherwise intelligent guy who spent an hour getting the pots back in a 335 using string. It usually takes me 5 minutes.
Everything goes thru the lower F hole. A few basic tools make this fast & easy: A long stiff, plastic-coated wire (I got mine from a garden hose package), a 6" curved forcep, and a set of T-nut drivers (from Stewmac). The forcep will pull & push pots, and the stiff wire is needed to get the neck tone pot back in place (put the wire thru the neck tone pot hole, attach to the pot stem & pull it thru; hold it with the forcep while you carefully put the nut on, and use a T-driver to tighten the nut without scratching the guitar finish).
Other tips:
-When you start, set the guitar on a table with an old towel under it.
-You need good lighting & a fan for solder fumes.
-Set another old towel on top of the guitar & set everything on that as it comes out.
-Never cut wires until you know where they go, and make a color diagram of what you have now if you're not sure.
-In case it starts looking like spaghetti, remember every PU, pot, toggle, & jack has a hot & a ground wire. The grounds are all connected in one big loop.
-Give an extra 2 or 3 inches of wires between each of the pots so nothing gets pulled tight upon re-entry.
-Test everything once when it's outside the guitar, and again when it's in place, but before you put the knobs back on.
If you get confused or frustrated, walk away & come back fresh. Ask if you need help.
