Can I put a 9.5" rim up front, or too wide?

A half inch more of width should not be a problem, the more important question is the offset of the wheel you're looking at. You would want at least the same offset as the stock wheels, if not less if you plan to go with a wider wheel. Here's a good website for calculating how different widths and offsets will affect clearances:

I just do not understand offset. Why is a higher number CLOSER to the center? I would think a higher offset = higher (more) distance AWAY from center...

Here is the description of offset from the glossary on the website I linked above:

"The offset of a wheel is the distance from the mounting surface of the wheel to the true centerline of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true centerline of the rim / tire assembly. This in effect brings the tire in to the fender well more. Conversely, a negative offset means the mounting surface of the wheel is behind the true centerline of the rim / tire assembly. This will cause the tire to stick out away from the vehicle."

I think the words make more sense when you look at the diagram from the website (see below). So a positive offset means the mounting surface of the wheel is father towards the outside of the wheel well than the center line of the wheel. The larger the number for a given wheel, the more the wheel will move inwards towards the body of the car. The front offset on the stock wheels is 32 for the 19" wheels and 34 for the 20" wheels. So for the 20" wheels, to have the same inner clearance as stock you will need a 9.5 wheel with an offset of 28.

We have used a 9.5" wide wheel in the front of the car, with good results. We used a 265/35-20 tire as our client chose to maintain the original tire sizes, but a 275 is possible as well. Our 9.5" wide wheel has a +24 offset, and fits nicely as shown in the photo below:

The higher the offset the more the wheel sits inside the fender
The lower the offset the more agressive the wheel sits out

You know more than you think. Higher number means that the mounting face of the wheel is a greater distance away from the centerline of the wheel. You are absolutely correct !!!

Any info on the rear width and offset used?

We used a 20" wheel, 10.5" wide, with a +30 offset in the rear. This was a good "reasonable" fitment, in that it was a good balance in terms of proximity to the quarter panel- not too close, but close enough to give an aggressive look.
