Well the Goldpact Knight definitely fits that criteria, an Imperial with no crafting. 

Speaking of that, do you know of any really morally good builds that may suit an Imperial? I really struggle with bad morality builds.

Again, bringing you back to the Goldpact Knight, who is basically quite honorable, he just doesn't work under the banner of a god. 

The Knight Cleric

Looking for a rather basic cleric, preferably little to no armor. I'm interested in using a good ol mace and conjuration and restoration. What have we?

Does anyone know of any good merchant builds? I kind of want like a philanthropist type character, but with some cool combat, illusion may be useful I guess? 

John Leblanc's Knight-priest of the Tenth Eye may do the trick. http://tamrielvault.com/group/character-building/forum/topics/character-build-knight-priest-of-the-tenth-eye

Ponty's Burglar is a straight thief-merchant who focuses on thieving and selling. No Illusion, but interesting. Lohzar and ShinJin's Knights in Iron build is also very good for merchants fm being a build with only Enchanting, Alchemy, Smithing, and Speech. Dark Paladin's Merchant Thief build is looking like what you may be hunting for, though. Speech, Illusion, and Enchanting for major skills with Sneak and Pickpocket as minors.

I want to play a blend between warrior and assassin, a stealthy warrior basically. I've used curses infiltrator and noodles shao'kai. Please help me

I've got this, both my Shadow-Guard and Lightsworn are Warriors that rely on using the Shadow Stone to add a stealthy approach to combat. The former is more Stealthy Battlemage, while the later is very much a Warrior (that does use a few spells here and there).
