If you don't want to join a PvP corporation that teaches newbies, such as Agony Unleashed, then take courses from them. They offer excellent training courses for non-members (for a fee), highly recommended.

Alternately, join Eve University, and take PvP courses, both from E-Uni, and Agony. There's no skill requirement for E-Uni, it's for training total newcomers. (Minor note, they are frequently at war, when recruiting is closed, so it may take time to join - but it's worth it). The Uni is generally considered a transitional corporation, most people leave it after they feel they're proficient, for other corps.

Update: R.I.P, Agony Unleashed. I can't find any articles on why, but they have disbanded.
