the only feedback I can give is: read the manual,. or get one of the many books out (Peachpit's Logic series are great for beginners).
The answer is: yes, get a midi interface, and a middi keyboard, install the drivers needed, boot Logic, and select EXS, then load the "Studio Tight Drums", kik is C1, snare is D and E1, flamed snare is D#1, etc.
