ooohhh, it's been too long since I was on EVNEW, and I no longer have access, I'm afraid, but maybe I can remember enough to help you.
If the ship .pcts are arranged in a grid format when you open them in MSPaint, you're actually really close to being where you need to be. I'm not certain what formats EVNEW can import, so if the next step doesn't work you may need to switch the file type with a "save as". (actually, after rereading your post, if you're copying and pasting into MSPaint, just save that file as a .bmp, and you can import into EVNEW from there)
Anyways, create a new 'rled' resource in EVNEW, then open the resource and head up to import (possibly under "file"). You'll have to specify what dimensions your graphics are in, though you're allowed some trial and error. However you should be able to set the horizontal and vertical dimensions of each frame, along with the total number of frames you have. Once you get the dimensions set correctly it should show up in the resource, where you can eyeball for any errors. (if your dimensions were off, it'll show up easily)
The same procedure is followed for importing the masks, which is done in the same rled resource as the ship you just brought in. You just have to specify what you're importing.
Granted, that was probably confusing as hell, but I hope it helps a little. :unsure: I remember one thing that helped me out when I was just starting was opening up a copy of Nova's data files and exporting some of the rled's there then trying to reimport them, just to figure the entire process out, since the exporting is pretty much just the opposite of importing.
If the redone ships are still the same size as their original counterparts, you can also check your dimensions in Nova's data files. I'm not certain if EVNEW lets you copy/paste between two windows, but if you have your plug open and one of the rleds is a match for one of your files (for instance, if you have a different colored IDA frigate, you copy the IDA rled over to your plug, then just import the new graphics over the old ones. you wouldn't even have to mess with the mask this way, either)
Edit: In fact, I'm beginning to realize just how useful EVNEW's ability to export and import entire tilesets really was.
