Alright, my new drums came today (Ludwig Classic maple

) And I've got a few questions on things like tuning and stuff.
I know the basic concept of tuning, and I have no problem tuning a drum, (well, most of the time) but I remember reading something about a technique that eliminates snare buzz when you hit a tom or snare. Something about changing the note of one drum or something
And the other thing is about putting my 13" tom on a snare stand. This is what I'm going to do, rather than using a suspended mount, but when I do this and tighten the snare basket, it chokes the sound quite a bit, and I'm just wondering if this is normal, and if a different type of rubber claw or something would help the matter.
If not, it's totally fine, and I can deal with it.
Thanks
