As a short stack here I think you're looking to find a hand or 2 to push with to pick up a couple blinds and keep yourself alive. The problem with this particular spot is that someone has already shown strength and will be getting 2:1 to call you, therefore pretty much eliminating your FE. I think the most important thing for you is to have your "first-in-vigorish." In HOH2 Harrington describes this as your best chance to put pressure on your opponents and steal much needed blinds when your M is low. Pick a spot where you can be the first one into the pot, thus putting pressure on your opponents.
