Thanks II Weeks, that's very close. There won't be a header since the joists will be bearing on the wall, however. Actually, all the joists will be doubled in the entry area because the floor covering will be rock and the doubled joists just below the stringers will be LVL.
If I didn't have to worry about the basement staircase, it would be easy; just build on top of the deck but I do need to have access.
If I use PT for the sole plate of the new basement wall, is it a good idea to wrap the PT with poly or does it not matter. It shouldn't ever get wet anyway.
I tear things down and build them up.

Based on the last drawing you will need a post at the corner which would neeed a footing.
You would not need a footing for the entire wall as long as you double up the joist as drawn.
I would go no bigger than 2'x2' x 1' thick and this may be overkill since this is inside and not affected by any frost.
