SSL Confusion - Help?

I am trying to get setup to do secure transactions with authorize.net and trying to decide what SSL certificate to get. I'm totally confused. Looking at GeoTrust certificates... there are 4 different ones with very different prices:

InstantSSL
InstantSSL Pro
PremiumSSL
PremiumSSL Wildcard

Depending on the reseller, the names of these are different. Can someone explain to me in simple english why I would get one over the other? I'm looking to A) protect my transactions, and B) have a recognized logo on my site that people can trust.

Does the certificate cover a whole domain, or just a particular url... I'm assuming its the domain. If I have multiple domains for the same site, do I still need to get multiple certificates?

If I'm doing hosting here, would there be an advantage to by the Wildcard option and then offer low cost SSL to my clients? Is that possible, or is it invalid because there are different companies there.

Thanks for the patience... I just want to do this correctly. Thanks.
