Man, that's gonna be a JOB!
Before you start cutting, drill a few holes in discreet places and see what you get. If it is cored it's better to peel up as big of pieces as you can so that it can be put back again. Saves some swearing in the end!

Landlocked: I'm not sure if the sole is cored or not. I plan on beginning to cut it out sometime in the next couple weeks and will then see what's under the sole.

I would epoxy saturate all the sides of the plywood, regardless of whether it is marine ply or not. Plywood, if allowed to get wet, will ROT, regardless of what kind it is.
As for cutting the fiberglass tape and removing the existing floor, use a fein multimaster or similar oscillating blade tool to cut along the edge. Most of these tools have a flush cut blade that will allow you to cut right along the hull side and leave a very, very clean cut.
You also don't want to have the plywood right up against the inner side of the hull. Ideally, you'd use fiberglass tape and thickened epoxy to tab the sole to the hull, but chances are very likely you'll need to rest the sole on stringers and floors and only tab the top of the sole to the hull—stringers run longitudinally along the hull and floors run athwartships the hull.
Tabbing is only generally strong in resisting forces in one direction... tabbing along the top of a cockpit sole will resist downward forces well but doesn't do as well if the forces are upwards. This is why bulkheads are typically tabbed on both sides but a sole is only tabbed on one in many cases.

Post some more pics of what you have ahead of you, is your sole cored?

|MIeagle||Alright thanks a lot Dwayne. Your last post answered a lot of my questions. I will be looking into the foam you suggested. You would consider that a better alternative than the 2 part foam that is poured then expands? I agree with your attitude of getting the right stuff and doing this right the first time, I just am beginning this type of work and am just learning what the right stuff is. Thanks again to all the replies.|

Are you absolutely, positively sure that noodles won't get water soaked after a while? I'm not. They weren't designed for long term immersion. Use the right stuff or don't bother.
Half inch ply is OK if it's properly supported; stringers no less than 16 inches apart.
Don't try to glue it down. Use the fiberglass tape and epoxy. It's far more stable.
You don't need to seal the underside with epoxy if you use marine grade plywood. The only need to seal the top side is to make it look good and prevent splinters. If you don't use marine grade ply then you will need to seal the crap out of all sides and do a lot of praying that it lasts more than a few months.
Use any good stain that you want to.

Dwayne, is there any specific reason you wouldn't use the noodles for flotation or is it just more of a risky proposition?
LandLocked, I really appreciate that thread you posted. I will really be needing some epoxy then won't I? How many coats did you do on that plywood? Also did you put glass cloth or anything on the other side? Also, I would like to try for a darker wood so is there any stains you would suggest using? Thanks

Thanks for the replies so far. This is all helping a lot. Is it safe to use 1/2" for the new sole and probably replacing the stringers in the floor? How many coats of epoxy would I use on the new sole? Also when placing the new wood sole in the boat, would I want to use fiberglass tape along the edge again or would a good bead of fast cure 5200 be sufficient.
Some info: the boat won't be spending long periods in the water or even uncovered. Also I bought it for just a few hundred dollars and its about 40 years old, so I'm willing to do work that has potential to backfire at least for the learning experience.

Here's a link to the sole work I did on my Oday. It's not super descriptive, but may help you. It's a little work, but anything can be done with enough time and money. I can tell you that epoxy is pretty expensive. I used most of a gallon doing just that small section of sole.
