ha kid don't waste your money on the most expensive pile of garbage, and yes I mean the vapor. That thing is overpriced by a good 400 bucks... but hey it's burton that's what they do. Try these brands for quality.

Avoid pretty much all the brands sold at those big retail stores "D&icks,sports check,sports authority,big 5 ect ect". Pretty much all the brands sold there "5150,Lamar,LTD,Sims,morrow" are low end garbage decks that any boarder planning to go a lot shouldn't bother buying, They'll only end up holding you back.
As for specific boards, without the type of riding you're looking to do "Freestyle,Allmountain,Freeride" that would be impossible for me to recommend for you :P.
and you don't have to wear a helmet, well some mountains require you to if you plan on riding the park. It's usually wise to wear one anyways, but if you don't want to I would find out if your mountain requires them in the park or not before hand :P.
As for the clothing just look at the tech specs, if you ride often in cold conditions look to stay above 10k on waterproofing and breathability, and look for fully tapered seams on the gloves, you'll probably want to have atleast one layer of thermals on underneath them.
clothing brands I would check out.
