Rinse them first, then sanitize and let the sanitizing agent (idophor, starsan, etc.) dry on your equipment. Rinsing them with tap water afterward negates sanitizing them.
That being said, relax. I'm sure your beer will turn out fine. Let it sit for 3 weeks in the primary and let the yeasts do their job consuming malts, fusel alcohols, diacetyl and everything else they can and you'll have a fine beer.
It's really hard for newbies to learn that rushing your beer due to eagerness and excitement is the usual cause of problems. Let the beer ferment three weeks in your primary fermenter then once it's bottled, let it sit another three weeks bottle conditioning. You'll be well rewarded for your patience.
