No stain.

Sometimes you can tell because of rust staining and buildup on the outside of such affected pipes,   but even without that they can be weakened considerably from their original state.On the drain side galvanized branch drains  (1.25 through 2" galvanized pipes)  can also rust out or clog up as the rust on the inside is very rough and catches hair, grease,  and other debris and will eventually need aggressive rootering,   which if the pipes have rusted enough may open up holes in them.I should note CAST IRON (hub and bell) old sewer pipe,  at least the 3" and 4" stuff seems to have a bit longer lifespan than galvanized steel;  it still rusts but doesn't crumble and flake and encourage blockages like steel does,   so an old house with a cast 4" sewer stack you may be fine for many decades more if you just replace all the branch lines going into it but leave the main stack.   

She speak of having to clean the carpet because there was a juice stain on it.

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.
