Looking to repot in the near future

[saladshooter]

In the near future I will be looking to repot my Npenthes into a larger pot and a larger place to hang it the web link to see my current set up is www.pushforcheese.com/Nep.jpg justs cut and paste, I need a suggestion on what/where and when to repot this plant. The pitcher that the picture is based around is 2.5" and the diamiter of the pop (soda) bottle is 3" I preferably would like a cheap alternative to letting the nepenthes to grow much easier if anyone needs any more pictures, I would be glad to show you more.
