Oil leak and power steering leak &/or pump issues. -256,xxx miles;

What is your question?

My car has been losing ALOT or oil recently and also power steering fluid. This started a few weeks ago. Well actually the pump been making loud growling noises so i kinda gad a feeling it needed to be looked at but both the leaks just started a few weeks ago. First it was the power steering fluid leak. The leak was pretty major but if i were to park the car, theres nothing on the ground indicating leak but the container would be empty or very low even though it was just filled. Then a week or so pAsses and i start losing oil like theres no tomorrow! So im filling power steering and oil every time i leave to go somewhere., and I'm. Not even going far. Like for work it takes me 7 min driving on hwy ( 3 exits away from home). I put in a quart. When coming home i put in a quart. And light flashes right when i get off hwy to home. But then again, before leaving home i put in a quart, drive 25 miles on hwy and the light dont start flashing til i exit off hwy, which is weird. So ive notice that when im on hwy and not stopping and going on small street, it takes longer for oil light to flash. So i after exiting, i stop at gas station, put in a quart of oil , start car and light dont flash and start going again. And when j get to stop sign i stop and as im exiting gas station, oil light flashes. Back to p/s fluid, all sudden i start up car to go to work and my car started up like a brand new car, no growling , squeaky noises coning from hood. :) was happy for a split sec there... Til i try to turn wheel and it was stiff. So i opened hood thinking fluid needs replacing but shockingly the bottle was still filled to norm line. So p/s was no longer leaking but im sure the pump is dead. And oil is just passing thru the engine. Also, oil somehow is getting on top of engine and surrounding things under hood. And for some odd reason, my muffler turned black and the back passenger tire/ rim turns grey/ black , as if its been charred. And whole back car seems like it got a coat of oily/greasy film. Even the top of my trunk is greasy, which makes me wonder how oil even got up there. I know wen the car is moving, theres drips trailing the cAr and it could be coming from muffler thats y muffler is Blackened, maybe...? Oil leak is so bad, its to the point im which a 5 quart oil is gone and doesnt even gets me thru 2 days. And i inky drive with ten minutes of my home now cuz making turns are killing my arms, and oil is just getting too expensive. So. Those are the details of my car issues. Are these easy fixes? I kinda think its gonna be pricy and might not be worth the fixes, meaning i dont think the car will last much longer anyways and its just too much of a hassle for me. I would like some input and advises. I dont know a lot about cars and issues. Im thinking about putting it up for sale. But i would like to know is it even worth anything, will it be better if i just junk the car or would someone actually wAnt a fixer upper? Leather seats are still very nice, the outer and interior is still very good with minor wear. Also, let me know what could be the causes of this and possible routes to go in regard to fixing it. One thing that got me confused is the p/s. It was leaking pretty bad then all of a sudden the fluids arent moving at all, whatsoever, its like a complete 180. Could it be clogged somewhere? *sorry for the misspellings and incorrect grammars. Im doing this from my iphone and so yea..*
