You might be getting a bit confused, as there are currently no intel native versions of Office or CS - there will be within the next six months or so, but not at the moment as the switch has only (relatively) just happened.
Dual booting isn't really that bad an option - with such a quick machine, it doesn't take that long to boot, just hold down the option key at startup, and a nice graphical menu shows you your options.
As for intel native OSX alternatives - NeoOffice is free, and many find it a more than good enough alternative, as it opens and saves into all MS Office docs. I don't know anything about pro graphics, so I'll leave someone else to answer that one.
