Filing taxes and the first time home buyers credit?

I always do our taxes and e-file but this year we are claiming the first time home buyers credit for a home we purchased in October 2009. I am just not sure what would be the best way to file?

1.) E-file taxes without claiming the credit and then amending to claim the credit?
2.) Paper submit all of it together?
3.) E-file 2009 taxes without claiming the credit and then amending our 2008 taxes to claim the credit?

Any advice is appreciated.
