Wheel Questions?

I have some beginner questions regarding wheels. I am looking for some on craigslist and ebay and am not 100% sure how to tell what will fit. When I first got my van I took it in for a safety inspection and was told the wheels that were on it had too large of lug nut holes. I wasn't aware that the wheels had different sized holes, I know you have diferent hole patterns 4, 5, 6. Anyways they never seem to list the bolt hole size? Any advice appreciated on what I need to look for. My understanding is I need 5 hole, 14" to 17" and something to do with backset?

Thanks

ok after doing some research and reading through the following

Could it have been the bolt circle they were talking about?
Anybody know what the bolt circle measurement on a 1st Gen is?

The bolt circle should be 5 X 4 3/4

Thanks malle. Hows the vans coming?

What does "offset is 10-20" mean? Everywhere I look it is described as -10 or -20 but the is an ad for some wheels that describes them as "offset is 10-20" does that make sense to anyone?
