When buying a drumset, I would recommend getting all drums for the same manufacturer and series. Otherwise the tonal qualities of the drums will not be consistent. The hardware and cymbals, however, can all be from different manufacturers. My main kit, for instance, is a Pearl
Export Select with Pearl
hardware and Sabian
, and Paiste
The tom that you linked to is an 8" diameter tom, which would typically be used as a first (high) tom. I really don't see drummer use 8" toms very often (especially for rock music) and very, very rarely do I see anything smaller. My drumset is a 7 piece (bass, snare, five toms...though I typically use it in a four to six piece configuration) and my highest tom is a 10".
My suggestion is to visit some music stores and try to find a good kit that is within your price range. Anything worth doing is worth doing right, so you should purchase a kit that will last you a while, but one that you can easily sell if things don't work out. I am a die-hard Pearl
fan, so I would suggest a Pearl
Forum kit (about $400, new with no hardware or cymbals) or a Pearl
Vision kit (about $500-$650).
You should buy cymbals separately. You can buy a cymbal pre-pack that contains a full set of student models cymbals, such as the Sabian
SBR performance pack, which contains a ride, crash, and hi-hats for about $230. If you decide to get more serious about your drumming, you will want to start looking at professional model cymbals. I recommend buying them individually, and ONLY after hearing them first (i.e. not through mail order). Every cymbal, even if they are the same size, model, and manufacturer sounds different...so you really need to play test them before buying.
On a side note:
Get drum lessons.
Seriously. Do this. Find a good teacher who has a good amount of gigging experience and who will teach you how to read music, play rudiments, and play a variety of different styles of music. If you don't do this, you will regret it if you decide to get serious about music and you have to unlearn a ton of bad habits.
Good luck and -- above all else -- have fun!
