Recording drums is an art by itself. Setting-up and getting sound on a kit is by far the most time consuming element of tracking. In the past I have spend up to 4 days work "getting-it-right".
A number of things come into play:
1 - Recording room. The better the acoustic environment, the better drums will sound. A kit is an interaction between a large number of acoustic instruments, in close proximity to each other, covering the entire frequency spectrum. The better the room, the better the sound. Recording in a good room allows extensive use of room mics, creating a natural, full sound.
2 - Microphone placement and microphone choice. Placement is part-of-the-art, and critical. I will mic one set entirely different to another, it depends on the room, the mics used, the kit, the player, and the required sound. Mics for grums have improved greatly over the last decade, specialist drum mics are now plentifull and not to expensive. For cymbals and room mics - unfortunately here, you need the best possible.
3 - A player capable of tuning drums - a sadly lacking comodity, tuning a kit is as important as tuning a guitar.
Other things - I have noticed time and time again that it seems now a standard practise to put stuff like compressors, limiters, gates etc in the recording chain, even before you hear one noise! These are all tools to fix things - leave them until (and if) you need them!
Ausrock - bleeding is totally natural (which is why positioning and EQ are critical). If you are playing around with the tracks, try the following approach:
Start by working on each track individually. TAKE TIME. Start with your kick. Get the sound right, don't stop until you have got what you want. Then your snare, then your HH, toms etc.
14 tracks, cool, you will have room mics and perhaps 2 on the snare, 2 on the kick.
If 2 on the kick, it is likely one will have been placed for attack (perhaps near the hammer), one for debt. It should say so on your track sheets. Start with the full one, get a nice deep sound, then use the attack, but reduce the low end on this one, just use it to give you the attack, don't get a fight between 2 mics for the other frequencies.
If you have 2 mics on the snare, one will be top, one bottom - for the sound of the spring / snare. Like with the kick, use them for what they are there for only. Like on the bottom mic - get the snare sound, shelve the low out, you don't need it (unless etc).(note: If you have 2 mics on snare, one trick for a fuller snare sound is to reverse the phase on the bottom mic.)
Do the same for each drum, and also for your highhat and cymbal mics. Remember there - all you need is the sound of your HH and cymbals, apply EQ to get rid of unwanted noise (ie toms, kick etc.)
If you have room mics as well - we'll come back to those after you have finished with everything else.
Now you have gotten exactly what you want from each track, one little note:
DON'T MAKE THIS MISTAKE: I have been doing this stuff for over 3 decades. If it takes me a day, sometimes longer, to set-up drum sound for a mix, do you really think you can do it in an hour? IT TAKES TIME - TAKE YOUR TIME.
Now you have everything more or less how you like it, time to start putting it all together.
Start with panning the kit as though you are sitting bang center behind it, but place you snare central.
bring up you kick(s), set it at a decent level. Next add your snare(s), and everything else, one-by-one. Get a good balance between all the instruments, create a group when you are happy with the results, so you won't mess-up your balance by accident.
Note: if you are using a DAW - don't forget to create a stereo master fader first, so you can see your overall master levels.
Now for your room mics - if you have them. Pan there sharp left and right - but LISTEN to them carefully, they should be panned in accordance to your placement of the kit!!
Set them up so they sound as good as you can get them, then feed them into your mix. Group them as you did with the rest of the kit, now play with both groups untill you are happy with the balance and sound.
You might want to consider using some reverb on your snare.
Hope this helps, start practising, and don't forget, its a lot of work, treat it like that, don't be satisfied easily, and you will get results.
