Easy way to remember the stud pattern is that it is a 3" square. This works out to roughly 108mm PCD which is how it is often quoted, but it's basically an imperial stud pattern.

The offset has to match the rim width, you haven't said what this will be. If you increase the rim width you need to juggle the offset, it is a compromise between keeping the centerline in the same place to give the correct steering characteristics, and keeping the wheel inside the arch and away from the suspension. If you keep the width and offset the same it will definitely fit.

If you fit a bigger rim with lower sidewall height this will affect the steering feel and handlng, so will changing the width and offset. Whether this is a problem depends on how much of a change you make, whether you're discerning enough to notice, and what other changes you make to the suspension to compensate.

Originals are 15" diameter/7" wide at the front and 16" diameter/7.5" wide at the rear. The offset seems to vary but typically 1" inset (25mm) front and 1.25" (32mm) rear.

IMHO that's too narrow. People generally seem to go for 7.5 rims and a 30mm offset, still on the narrow side but widely available to suit the Astra Bling Boys. 8" rims with a 27mm offset and 215 or 225 tyres at the front and 235 or 245 tyres at the rear may be more suitable.
