Get your CFII, and do all the instrument instructing you possibly can. Especially if you can get into actual IFR conditions with the student. Try to schedule as much as possible at night. If you go to a different airport for approaches, do a touch and go, and then you will be logging night IFR cross country time, which will help you get hired. If the T&G airport is more than 50 miles from the departure airport, then the student also gets to log cross country time towards the requirements for the commercial and instrument tickets. You get to log cross country time towards the ATP minimums as long as there is a landing at a different airport from the departure airport.
With respect to the multi, if you get hired as a CFI, generally the school will give you a discount on multi time.
