Well, being honest, if you go just for the looks, you should look at 8.5 or 8.75" wide wheels. Since you're going for 245 or 255 tires, there is no need to go for 9.5 unless the wheel design fits you better. There are however also concave designs out there in 8.5" sizes (look at my journal for a example, link in my signature)
If you insist on 9.5" be aware that they will poke out quiet a bit due to their size. You can add spacers, however, this will add to the amount the wheel is outside the wheel arches.
Example. A 8.5" +35 wheel is about flush. Take a 9.5" wheel +35, it will 12.5mm poke outside your fenders. Do a 9.5" wheel +48 and it will be flush again, but will be rubbing inside. You can add now spacers (like a 10mm each side) however this will add again 10mm, so it will poke again 10mm. In the end, a +48 wheel with 10mm spacer is like a +38 wheel.

Spacers do add stress to your suspension, specially the ballbearings (I hope they're called like that in english). If you have the choice, you should buy wheels that fit without spacers.
If you take the right springs your daily ride confort will not be compromised. Generally you can say the stock dampers are good for a lowering up to about 1", if you go below that (some springs are 1.5") the dampers should be changed to sport dampers. If you do not do this, the ride confort will suffer.
My suggestion, take the Eibach Pro Kit (Not the sports line!), they are very good in quality and also ride confort
