ITs quite possible I will never have a free weekend again... or not for a long time! Still in the very early stages of the "this old house makeover"!

SO today we (Mom has been helping out a little too) loaded up the yard debris we cleared up last week onto the trailer to take to the dump, we had 3 piles larger than this one pictured....but by the time we got it loaded the dump was closed! grrrr so now I will have to wait till next week to take it...I could get up super early before work one day this week and take it,,,,but I donnnnntttt know about that. That would be a days work before a days work!
Meanwhile I am taking one room and getting started on the "make better". This room has a couple of issues but the main one is the FLOOR! I was so busy I forgot to take a proper "before" but if you look at this photo Ive shown before and the room at the end with the double windows you see that tan carpet?
Underneath that is another carpet a brown shag from the 70's --Groovy right? WRONG-
I hate carpet..this was the LAST ROOM that needed to have carpet removed well and that french glass door leads to a small room we called "the Office" it was where we kept a desk and all our paper work, it has carpet and that will be removed too...
ok it has 2 layers of carpet too..but the dining room has the 2 layers of carpet and A layer of TILE! And the tile is on a underlayment sheeting and trust me they used long nails every 6 inches square when they put this tile down back in probably the 50's?
You cant really see the tile this black stuff is the remains of black carpet padding that stuck to the old tile...
and under all that is the pretty pine wood floor that has never been finished! Once this old stuff is literally "peeled" off with Intensive back breaking labor, the wood floor will get sanded and varnished to hopefully match the other floor! IT took me an hour to remove this one section that's about 4 x 5 and it looks like there's about 4 more of the same! Probably take all day tomorrow to get it off!
LOOK AT ALL THESE NAILS..I dont think the fellow that put this down missed one single nail and these nails are 3 inches LONG!! I mean really? Did they need this many? Holy Moly!
Im trying to not do too much damage to the floor underneath but Its not easy!
I'm half way thinking of doing the same in the kitchen, can you PLEASE talk me out of it?
PLEASE, enlighten me as to WHY I dont need to do that! It has Vinyl on it now and I know there are 2 layers of that and possibly a layer of linoleum under that and a layer of this horrible underlayment with nails every 6 inches!! AND yes the dated curtains are gonna go too!!
Footnote: to anyone reading this as of today, June 14, 2016 here is the finished room
