Hmmm... a lot of the technique in making "good" graphics depends on your own tastes and what program you are using, but I'll do what I can to help.
I find that sketching on paper first is a good way to create an initial design. When working on a computer, I tend to become perfectionistical (? ) right off the bat, which is not helpful for getting an initial "feel" for the ship (or outfit) in progress. The result of course depends on your personal preference; myself, I like sleek, streamlined designs rather than more boxy "realistic" ones like, say, the Millenium Falconลฝยล
Once I have a pretty good idea of what I'm trying to make, I start modeling it, using only simple solid-colored textures at first. This part really depends on your use of the capabilities of the software - extruding, lathing, skinning, booleans, organic modeling, etc. Although it's pretty hard to make a ship out of nothing but primitives, most "fancy modeling" isn't really necessary; a few extruded fins or Boolean operations can do wonders for an otherwise simple design. (If you've played Secession, all of the new ships and outfits in there are composed almost entirely of extruded shapes and ellipsoids - no organic modeling or other complexities)
Only after I have the shape essentially finalized do I really worry about textures. This again depends greatly on the program used, but it's usually not too difficult. For "high-tech" streamlined ships like the Strands or in Secession, all that is really needed for good looks is the right surface properties (diffuse,specular, etc) and maybe a bump map; "low-tech" ships may require more complex textures to look right.
Hope I've helped...

PS: re the quote about the trouble matching existing ships - it's true. Why do you think I decided to create a new govt altogether?
