That sounds like a very good plan to me, just make sure to get the most credits transferred to U of W that you can get. For orals, study everything you can get your hands on...all the books you have, FAR/AIM, oral exam guides are just the beginning. Look on the internet too, just search "private pilot study questions" or "faa instrument rating questions," something to that effect and you'll find quite a bit of study material. Also, ask yourself different scenarios, issues with the airplane or emergencies and what is the proper and best solution to deal with it. I would recommend getting the MEI if you know you'll have multi students to train. If not you might just want to get up to CFII and start training students to build up your time. You can usually find someone to split multi time building with you locally just ask around the airport for someone who owns a light twin, see if you can fly right seat with them when they go on trips or just take a spin around the pattern...you'll be surprised at how many pilots love helping other pilots out and also love to show off their airplane by taking you up...its like a win-win for them and you. If you need multi time quick you can pay places like air-ben in florida and they'll get you as much as you need. Hope this helps.
