I agree with everything thebigbaker said.
On the sanitization note: New homebrewers (myself included) are way too worried about post ferment sanitation. Once the yeast ferments the beer, it is very inhospitable to bugs. A few bacteria falling into the fermenter are not going to cause anything problematic. If you can't pull a sample (or add hops) without infecting your beer, maybe brewing isn't for you
Remember, Relax, Don't worry, have a homebrew.
Or as I like to say, "It's still going to make beer."
