Hellow gmb_sim,
First of all, do you wear any protective brace on your knee? Because you have to. Any way you can use cryotherapy. (Put a towel around your knee then apply ice massage.) Also you can elevate your leg slightly over a pillow. This will help decreasing swelling and pain untill you see your surgeon. Quick release of swelling is important. You are now in what we called "Maximum protection phase" so you should walk with partial weight bearing by 2 crutches or walker. Your exercises are fine but it's not recommended to full extened your knee in the first week. Focus on your hamestring, that will help. Any exercise should be pain free.
Don't worry about walking stuff, it may takes 4 to 6 weeks before you can walk independent. At last, I think you have to find a physiotherapist cares about you. Good luck!
