I can also recommend the book T.A Drums Drumset Tuning Theory by Tony Adams. find at http.

After initial seating in of fresh heads (important) and tensioning down to the ball park, i find drums don't take long at all to tune up. Good heads are a must.
I usually put all the toms out on a piece of carpet and tune each drum so head tensions are equal and at the desired tightness for the pitch i want. I check the head sounds the same at each tension screw (with thumb centre head) Then turn over and repeat on batter head.
Then i place the toms on the kit and tune them for the seperation and tone, and blend that i like. Often it's just the turn of one tension screw.
Then at the gig, (naturaly each venue is different), i will slightly adjust if needed the botton heads only, higher for the reverb room so they cut through.
Kick and snare i leave pretty much as is, and give them an even tweak when the heads start to flat.
All up a general tune around 20 minutes.
It can be confusing when you start and easy to be distracted, that's why i line all the drums from small to big and work methodically through them.
You get better with practice and with a focus and knowledge to get exactly what it is that you are trying to achieve, get the book.
And try to listen out front of the kit, they sound different from that perspective.
I learnt that lesson years ago when i was listening to a local drummer who sounded great. I was given the opportunity to play on his drums and from the throne they sounded dreadful. He used his soundman to guide his tuning, it works.
