struggling with drumsets

im having trouble with the drumsets. i have a handful of questions to ask about them that i cant seem to find the answers for despite searching forums and googling answers.

• can i sample drum sounds?
  id love to hear each sound without having to insert it in my piece and try and figure out if the sound suits what i need. i cant find any sort of way to test things out without putting in a noise and listening to it, removing it from the rest of the pitches and trying again.

• looking for fingersnaps
  i noticed that the finger snap noises do not sound like fingersnaps, and i saw someone suggested that 38 hand clap is a good alternative. are there any similar sounding drum noises? im hoping for variations of that pitch,,

• customizing drumset ???
  is there a way i could just replace one noise with another? im struggling to try to find a method (i dont work with percussion or any sort of drums in real life so i dont understand the music much, i play violin lol imvery sorry if im horrendously mistaken / very confused)

im really new here and this is my first time ever using this sort of app. ive been working with it for hours and things have been going smoothly, just that id like to have some nice beat / rhythm in there... i apologize in advance if ive posted this in the wrong area, formatted wrong, or am completely lost and confused
