Do not start on a long board! It will only handicap you. The old guys and brainwashed young guys use them because they are to weak to paddle a real board, and the young guys' surfing remains stagnant as long as they are on them. Start on something about 7'6" or so up to about 8'. A 4 mil suit with a hood is all you'll ever need - the new rubber is awesome, but there are decent suits out there (name brand) without all the bells and whistles for under $200 - depends on how much and when you are going to surf for what you will want.
And to all you d-azzes out there that say "Surfing sucks, don't start," Stay outta the water then!
