A wetsuit is a good idea, but that depends a lot on where you'll be diving. The style and level of protection are entirely dependent on the water temperature and type of diving you'll be doing. If you don't know for sure right now what that will be, you might end up with a lovely wetsuit hanging in your closet most of the year.
You can get pretty good quality entry level regulators (1st and 2nd stage) for less than $200 from Aeris, ScubaPro, and Sherwood at LeisurePro.com. All are good brands. You'll have it your hands in about a week from LeisurePro. (I have a ScubaPro MK2/R195 and it's just about bullet proof. It won't breath as well deep as the Atomic's and others, but it's also half the price). A decent Octopus will be $80-$100. Another $100 for a console. You're probably looking at $400 for entry level regs.
Or, you might see if your LDS will sell you a multi-dive package that includes equipment rental. See if they'll deal with you for 15 or 20 dives. Then decide what you'd like to invest in first. If they're a good shop, they'll let you test dive equipment before you buy it.
