Default Dealing with diminutive digital images

I've got a digital photo that's about 5.5" wide. I need to use it about 8.5" wide on a magazine cover. Ouch.

How do I determine the best course of action -- upsample to keep it 300 dpi, or just enlarge it and let the resolution drop to 195 dpi?

It will be offset printed. I normally insist on 300 dpi, although I don't always get it, but I don't think I've ever run a cover image at less than 230 dpi, if that.

(This is one of the images that has the chromatic aberration discussed in another thread, but the client is going to live with it.)

If upsampling is what I need to do, what's the best way? I'm using Photoshop 7, out of force of habit, but also have PS CS2 installed. If there's a plug-in that works better than whatever's in PS CS2, I'd consider it.

Or is PSP better for upsampling?

And if I upsample, should I avoid sharpening? Will that make it look worse? What's the best tool to use for sharpening?

FWIW, after I do whatever I do (which has to be done in the next couple of days), we are going to get an Epson proof from the local service bureau, so if it looks horrible (either because of the size/resolution issue or the chromatic aberration) my client might opt not to use it after all.
