On the Pentax side I plan to pick up the DA 21 and 40 Ltds after I sell the Tamron.
As one who own way too much lenses myself, I'll give give a bit of tough love regarding your lineup
Why keep the Helios 44K? It's not really fast, it's not very practical (green button only), and it's not that much longer than the 50mm ? The 50 1.2 and the 77 1.8 would probably be the lenses you'll grab anyway?
There is also the question of the 35 macro. If you use it for macro, fine, otherwise I would guess the 31ltd would do the job perfectly.
I wouldn't bother with the DA40 if I already had (and liked) the FA43. I went for the DA40 myself as I didn't feel too comfortable with the oof rendering of the 43 wide open, but can't see the point in having both. One of them is bound to become a dust collecting item.
The 21 is a nice thing to have though. Great for general shots without screaming "wideangle" to the viewer.
