The place is not that big and pretty busy but don't be intimidated. The staff is extremely helpful and tolerant of beginners. If you want to find the most common generic part go to Home Depot. If you want to find everything else and get some good advice go to Lincoln Pipe.
I have done a fair amount of remodeling but I am pretty much an amateur. Whenever I have needed to find the right part or get some advice on fixing something I have found Lincoln Pipe to be the best place to go. A friend of mine who is a pro designer uses them all of the time and recommended them to me.
