Procedural Star Sector, Again! 8-P

I want to take another run at a 3D procedural star map, based loosely on this- (link here). I made some stars based on position. (Why, yes, I have done this before! 8-)
Now, to move around, In! Spaaaace! using the pointing device... I will need to save a box of star systems for that, as I need to derive some angles and do some math on my box of star systems. Then, when we move, we need to know where we are, which way we're looking and we need some coordinates to feed into the star system generator so we can regenerate some of the same stars and make some new stars, all based on position. Ugh!
