Well, your best option right now is to use Parallels off of the Boot Camp partition. Only real downside to that option is that you can't pause the VM, since then it wouldn't be bootable from the partition. It's the exact same partition, so other than purchasing a license of Parallels, there is no downside or risk to this approach.
For Chrome, use the mac version.
For office, if you really need specific Windows features like the equation editor, then run it in Parallels.
For newer games, you'd want to go back to Boot Camp.
I use Parallels, I do not have Boot Camp, as I prefer to keep all 640GB in one nice big partition for all of my junk, and I like to multitask between XP and 10.6.x.
Note that Parallels is highly disk I/O bound (as is just about any Macbook C2D), but memory intensive (4GB needed for a decent experience). If you have an SSD or can run a VM off of an external drive, the performance will go up by an order of magnitude. For me, it's gotten to the point where I will often close everything and reboot before going into Parallels, which I guess sort of defeats the point of it.
