Best Credit Card Company

While I appreciate all the credit card payment options, it makes it difficult for the beginner who is trying to find the best one.

Can you point me in the right direction regarding a few credit card companies. I am just starting out and only making a few sales a month, so I am wanting an option that has low or no monthly fees. Basically, I am looking for something like paypal, but I would people to be able to pay on my website instead of having to go to paypal. What are the best options here?

Second, once sales pick up, are there 3 or 4 options most people prefer?

Last, I'm assuming I'll need to change my site to a secure site. If so, is there a way of doing this only for the store? I don't want to break the links to my site and the links within my site.
