What I did was pick up a 20 gallon Rubbermaid container, and soak two pieces in them. Filled it up just half, because I was too lazy to change all the 20 gallons at a time. Changed all the water every 2-3 days, and in a couple of weeks, the water I was changing didn't have any tannins in it, so in the tank it went...
The first ever piece of driftwood I bought didn't have the same problem for me, so I guess each piece is different. So for some people, removing the tannins from the wood using my method may take longer, you just have to judge for yourself when you can put it in your tank. I used hot water for every water change, and the reason I didn't boil the wood was because I don't have a pot big enough.
As for live plants, what sort are you planning on planting? I have some java fern, and that seems to be pretty popular and easy to grow.
