Jump right in, it's not that hard. All you're doing is soaking grains in hot water, ~152, then rinsing with more hot water. The best advice I can give you is to make an immersion chiller. Just get soft copper coil, it is used for running water to refrigerators, I'd recommend 50'. Then grab a paint can or corny keg or some cylinder about the same diameter. You just gently wrap the copper around your keg and then put fittings on the ends. Just like that you spent $20 less and got a 50' IC instead of a 25' IC.
