Piping Help

I want to clean up the piping and replace the valves under my kitchen sink before I install the new sink and faucet with PEX supply lines.
How do I replace the valves and get rid of all the piping ABOVE the new valves? And will the new PEX supply lines coming out of the faucet fit right into the new valves?

Remove the valves and replace with this:

But I like those old valves that you have and if they still work, I would keep them. These new valves are garbage. If you decide to keep them, all you'll need is this adapter to screw into the valve:

You could rebuild the old valves with a new washer and some string packing if they don't work. instead of replacing them too.
Be sure to use 2 wrenches and seat the back of the wrench against the pipe so you don't crush it.0 -
Yeah, the valves are broken. I like these options you all are suggesting, thank you.

Above the valve consider the braided silver flex lines from the home center (assuming you are not in a high rise). There are different sizes. Most modern kitchen sink faucets and angle valves need 3/8" at both ends but you might need 1/2" at either end depending on what's there. You probably need a basin wrench to reach the faucet.0
