I've got the cutting table/ironing board height thing solved... they're one & the same... got a big-board for the ironing board, and a cutting mat that's the same time. That way I can raise/lower it depending on if I'm standing or sitting. I have the board perpendicular to my machine table, so if I'm doing something like paper-piecing which requires lots of ironing & cutting along the way, I can have it at sewing-table height, but if I'm doing LOTS of cutting or ironing, I raise it up & go to the other side where i have lots of room to move. Only negiative is sometimes I wish it was wider for cutting, but I've solved that by standing at the end & cutting on the long-way of the board when I'm cutting something particularly long.
Of course none of this is ideal, my sewing table is a card table, but it can all come down when I have to transform back into a guest room, and one of these days i'll get a "real" studio.
