squatting is a stain on our industry..

The carpet you both picked out, stained and ruined?

My current cabinets are a medium/dark wood stain. they look great for what they are, but I have seen a lot of people paint them and they look great, but I also didn't know if I should just leave them the way they are. 3.

After you purchased new doors look into Java stain.

Pretty much all the lower end non custom stuff is from there, but they are stained/painted and assembled in the USA.

Then you could buy the doors and drawer fronts from a surplus building supply store and stain or paint to your liking.

I ask them on paint color, hardware, floor stain/finish etc.

It might be worth a try, it is far superior to Kilz as a stain blocker. 

I'd suggest not noting things like "stabbed coach with a knife" and instead "7" long cut in left cushion of couch" and "4 sq ft area of carpet under den window coated in an unknown substance that stained the carpet". 

Rather than perform tests to make life more expensive these simple steps will cure most issues.Yeah, Killz can be a great solution for covering stains, especially smoke related.
