Sorry to hear that, but yes, that does seem like it's burning oil. That doesn't necessarily mean a head gasket leak or other damage to engine internals.. but that's usually what it means.
If you remove the hoses connected to the PCV valve and look inside of them, is there any residue/sludge building up? If so, cleaning that out might get you to squeak by the emissions test. The fact that it smoked less after you changed the PCV valve is a good sign.
But if that doesn't work, I would get a compression test gauge. It's an easy test to perform, and it will tell you whether you have internal damage that's causing the excessive blowby and oil consumption. It should cost about $30 and it will confirm if you should cut your losses at this point or not. If you have low compression in any cylinder (or all of them), it's going to be expensive to fix, whatever it is. If you have good compression, then have a pro look at it and see what the issue is.
