When I was non-weight-bearing for 8 weeks after fracturing my pelvis, I used a walker. My DH made a simple tray for it out of household materials he had around in the garage, and it enabled me to make my own meals and carry stuff from place to place in our house. We had a 2-story house, so I was limited to downstairs until I learned to butt-scoot up and down stairs! 
I was extremely lucky as my manager allowed me to work from home, first part-time, then full-time, until I came back into the office at 9 weeks when I was cleared for driving. That meant that the physical therapist came to my home, I could rest or nap when needed, and I didn't have to dress nicely! Doesn't sound like you will have that option. I was on full pay with our company's short-term disability for the first six weeks and only started working from home part-time the last two weeks of that time period. Does your company have any short-term disability policy? If so, it surely seems like not being able to drive would fully qualify you for it. I can't imagine they'd require you to come back to work immediately after surgery when you probably need to be resting and doing PT as I did.
After my six weeks, my disability would have changed over to long-term at just 60% of my salary, so I worked full-time from home after that until I could go into the office.
I only used crutches for a couple of weeks and hated them! After getting used to a wheelchair and a walker, I found them scary and hard to maneuver. I was always scared I'd fall over backwards! By the time I went back to work, I stopped using crutches completely and just limped. That gradually stopped as well.
I surely do wish you well! As you're now realizing, your athletic schedule is the least of your worries at this point, as mine was too. I was injured while on a training ride for a spring century. Needless to say, that year's training went out the window, though I did manage a 50-mile event in the fall!
Good luck!
