I didn't make explicitly clear that the ratio I was referring to is 
simply the ratio of width to height. In your case, as I suspected, it's 
4:3 (5152/3864 = 4/3).

To crop your image to completely fill a 6x4 (i.e. 3:2 ratio) print, 
you'll need to make the shorter dimension 3435 pixels (5152 * 2/3 ≈ 
3435). So a total of 429 pixels need to be removed; you can control how 
much of that comes off each side.

Resizing won't help unless, as Gary mentioned, you distort the image by 
stretching more in one dimension than the other. That may be an 
acceptable alternative if you don't want to loose anything from the 
edges by cropping and don't mind the slight distortion. If I was going 
to do that, I'd keep the shorter dimension as it is and increase the 
longer dimension to 5796 pixels (3/2 * 3864).

Definitely a good idea! I usually keep the originals even once I've got 
the final result I want, just in case I want to go back and do something 
different.

No problem. Hope it works for you.
