i applied schengen visa through the embassy few years ago. They only issued the form in certain amount. Lets say they only have 40 form for 1 day, you will have to come early in order to receive the form.

Best you get the form first, and they usually will give you list of what documents need to be submit. Most of schengen country requirement are all pretty standard. Hotel booking, flight ticket, 6 mths salaries, insurance , sponsor letter, photos etc etc.
