I hope you have solved the getting up without help every time issue.
Here's what my PT taught me to do which made life much easier on that front.
When you are on the front edge of the chair or edge of the bed that you are rising from, and ready to stand, lean forward some and get your center gravity moving out over your feet as you stand.
The mechanics are vastly better, and if you notice it is what folks do all the time who have not just had their hips done!
You may wish to have your walker in front of you and one of your helpers with you and experiment.
I just had my second hip done on 5/15 and this trick learned on first hip in February has stayed with me!
Best wishes on a successful recovery,

I strongly recommend prunes (I got the Sunsweet indiv. packaged ones- I actually like them esp. compared to the alternative of drinking prune juice) and drinking lots and lots of water. Activity should also help. I had lots of gas, then a BM on the morning of post op day 2. I'd much rather hit the issue head on before it gets too painful! Good luck- sounds like you're doing great!
Walking to the bathroom... And sleeping! 
Plus I walked downstairs once a day from day 5, to eat a meal with my family... Then went back to bed! 
So in total maybe half a dozen little 'walks' a day, mostly just about 6-8m (including there and back), and two about 12m (once to the table, and then back after the meal).
