I am a first time switcher and the only thing holding me back is the Graphics Card in the High end MacBook. Is it 64 bit?
I'm confused by what you're asking. Are you asking if the GPU in the Macbook is 64-bit? That doesn't really make any sense. If you mean the CPU, Core 2 used in all of Apple's systems except the Mac Mini is 64-bit, though the Macbook can only address 3GB I think (the Macbook Pro can use a full 4GB now).
Does anybody know when the next Office will release?
Regarding Office, it will most likely launch later this year-that's what Microsoft keeps seeming to imply.
Personally, if you can, I'd hold off on buying Office until the next version comes out, since I'd hate to buy Office 2004, and like a few months later have to buy 2007.
As mentioned, you could try a free Office program. But I'd recommend Open Office instead of NeoOffice. NeoOffice is based off of Open Office, but it's based on an older version I think (1.x) instead of the current 2.x. Right now Open Office uses x11 instead of the regular OS X Aqua interface-if that doesn't mean anything to you, it just means the interface is a little different from other Mac programs (the Menu bar is at the top of windows, instead of at the top of the screen), but it still works normally. NeoOffice probably looks slightly more Mac-like, and I think uses Java for it's interface.
But I'd really go with OpenOffice over Neooffice. More developers have kicked in recently to get Open Office using the native Aqua interface.

here's some screenshots of the current OS X version of Open Office (one of them is in another language, but you get the idea)

Open Office (and NeoOffice) read and write Microsoft Office files, so they may get you by until Office 2007 comes out. Or you might decide to just keep using them.
