Get the equipment to do it. Obviously, with all grain brewing, you cannot do partial boils. You need a kettle big enough to do full boils and then you need a turkey fryer to do the boils as MOST stoves cannot produce enough heat to boil more then 4 or 5 gallons. Secondly, get together with someone and PAY attention. Take notes, and ask questions. Lastly, do some research. Read some books. How to Brew by John Palmer and The Complete Joys of Homebrewing by Charlie Papazon are GREAT books with a TON of knowledge. That's my advice for you.
