Andersen window
I actually think Tom may have misidentified your balances, at least partly. The two balances in your window I think are a closer match for our 24-R12-827 and 24-L8-1227. These are designed for Andersen cottage windows where the top and bottom sash are different heights.
However, from the sash dimensions you gave (28-7/8" x 34-15/16"), your window has the top and bottom sash being the same size. Can you confirm that that's the case? If so, I would recommend the 24-1231.
The window latch set you show would be 90-095.
Thanks for confirming. It definitely sounds like you have a cottage window, so go with our 24-L8-1227 and 24-R12-827 Andersen balances. These should work for you.
