Samyang 85mm f1.4 - still available, price reduced to £195.00 inc P&P (UK).

Ebay is the best place I think. I'd forgotten about the Yongnuos. Excellent idea! (You could use your Sony version as a second flash using the built-in optical trigger).

Up to you Suzanne... it doesn't look like an exceptional lens though, and you'll have to buy an adapter costing about 10 quid for a very cheap Chinese one, and quite a bit more for an original Pentax one.

Personally I would not want to buy a flash which didn't tilt (or swivel). If you want to keep costs low, I would look at one of the older units (e.g. the AF280T, which I can wholeheartedly recommend) which allow you to bounce the flash off ceilings, and walls, for much more natural looking results. (There's an AF280T for sale in the classifieds).

The older flashes lack the fully automated PTTL mode, but using them in manual is a doddle (just adjust your aperture and ISO!) Pentax flashes will be safe for use on your DSLR, even the older ones.

You can buy an M42 to K-mount adapter, but personally I wouldn't bother unless you intended to invest in other M42 lenses. I would send the lens back since it was incorrectly/poorly listed.

Ouch! The sound of those hurled cameras smashing on the ground goes right through me...

Come on Don... I'm sure after many years in the profession you must have a few cringe-making shots (client to blame of course!) Let's share our 'regrettable images'...
