VFTs are pretty tolerant of transplanting.
First you need to decide if you are going to simply move the entire contents into a larger pot, or divide up the clumps into individual plants. Then prepare enough pots and media for your needs.
If you are going to just transplant into a larger pot the procedure is pretty basic. Take larger pot and fill with media, remove plant from old pot (it should all come out in 1 ball) drop ball into new pot and fill in around the edges. Some people like to put a handfull of long fiber sphagnum moss at the bottom of the pot to keep the media from escaping through the drainage holes. I personally have never had an issue with loss of media but if you have the sphagnum it wouldn't hurt. Then water the plant to "set" everything and voila.. all done.
The only difference if you are dividing the clumps is that you should take care to do as little damage to the roots as possible. I find that the sprayer from my sink works well to help tease apart the root systems of clumped plants. You should have all your pots prepared with their media before you start disassembling the clumps though. You don't want your exposed roots drying out on the table while you are busy mixing peat and sand and filling pots. Basicly as you get 1 plant seperated, poke a hole in the media of its new home, gently push the roots down into the hole till the white part of the plant is at the soil level, pack the media around the base of the plant a bit, and then water it well to "set" it in the new pot. Continue till you are out of plants or pots (or both) and voila, all done...
Good luck

Edit: One thing I forgot to mention. Don't stress over tripping the traps accidently. You are GOING to trip them.. just accept that and don't worry about it. The plants may look a bit ragged for a while after transplanting, particularly if you seperate the clumps, don't be surprised if none of the traps work again or many older leaves simply die off completely. This is normal and not a cause for concern. As long as you have green growth comming from the center of the plant you are fine.
