Start with a good reloading manual such as Nosler's or hornady or Sierra.
Buy an RCBS Rockchucker kit and you have the starting set up. Pick a cartridge that you wish to start with and buy the componants, i.e., brass, powder, bullets and primers. Follow the instructions in the beginning of the book to start reloading.
If you have a friend or aquaintance that reloads, have him come over and help you set up your equipment and help you start loading. The basica are easy to learn, its the little tricks and tips that take time to learn.
Good luck!
