Advice > retouching pic from friend's 450D for contest

A workmate recently asked me to apply my (limited) Photoshop skills to retouch some bird pics he was entering in a contest for a magazine.

I did some basic white balancing and a little sharpening on them in Photoshop (CS5) and now one of the pics has been shortlisted and will be going into an exhibition. Now I'm at the edge of my experience so I'm hoping some knowledgeable folks here can give me some advice.

He used a 450D at ISO500. I was pretty impressed with actually and just about bought one. The pic is 4272 x 2448 at 72dpi. Initially I reduced it because the requirement for submission was that it was under 1mb.

Now the contest organisers have given him some more specs we have to meet, the key ones being:

- "Resolution at least 2600 pixels on the longest dimension" > the longest dimension is 4272 so this isn't an issue

- "Ready to print at exhibition size (approx A3). Therefore, allowed adjustments must be a sufficiently high quality to handle the upsizing for printing (the print operator will do the interpolation/upsizing)." > need some advice here

Are the image dimensions from the 450d enough to print at A3 approx with any resizing? Do I need to boost the resolution to something higher and re-sample it or somethinglike that? If so, which one is best (bicubic etc?)

Any advice would be very much appreciated.
