Hi Phoggie,
I went to a local medical supply store and bought the "hip kit". it comes with a reacher tool, long handled sponge, long shoe horn, and sock thingy. It was about $30.00. Well worth every penny!
I got the crutches from the hospital when I left, I think they'll provide a walker too. i would just ask.
As far as the potty chair. My recommend, if you can, have someone install a higher rise toilet. My friends came over and remplaced mine and I love it!! I also installed handicap rails which are very helpful. you can get the rails at a medical supply store too.
If you don't have a walk in shower you may want to get a tub/shower seat. I used mine for about 4-6 weeks. Also, at a medical supply store.
good luck.
Ginny
