The best advice from any diver will be "just do it". Your basic swim requirements for your open water certification are:

200 yard swim - No time limit
10 minutes tread water

You will need to have your own mask/fins and booties/snorkel for the class, but all the SCUBA gear will be provided. Most dive shops will offer a gear package that you can purchase during/after your training for a discount. My personal recommendation is to get through your training before purchasing your gear so you have a better idea of what you want before spending the money.
