That's kind of a tough question to answer since you haven't stated what you want to be doing with your ipad. Offhand your options are to:
1. Manage your video and music library a bit better and trim them down to size a bit. iPads have good battery life, but you won't listen or watch EVERY song and/or video between charges.
2. If size and your available funds are more important than the modest speed increase, return your ipad if it's within the 2 week window and get a 64 gig v1, either online from the applestore, or possibly craigslist.
3. If you need more storage and speed, return your pad if possible, and wait it out until you've got the funds and the ipad version you want is readily available. Once the 2's ship for a couple more weeks, supply and demand will even out a bit and slowly bring an end to the ipad 2 feeding frenzy that's currently happening.
