Cousin Eddie,
Roads entering the park
East- HWY 120 Tioga Pass, the route from Mono Lake to the Park entrance rises 2500 feet at an 8% grade.
West - There are three:
HWY 41 out of Fresno,
140 out of Merced (easiest Route),
120 out of Manteca.
Coming from AZ (assuming your route) HWY 41 out of Fresno or HWY 120 over Tioga Pass are the best routes by location with Tioga Pass challenging.
Crane Flat to Yosemite Village is just over 15 miles with travel time of 30 minutes, not to bad.
As others have stated parking could be a challenge, weekends and holidays are the worst from a parking perspective. My observation has been that if you arrive early (7:00 - 8:30 ish) you should find parking at Yosemite Village, large vehicles park to the back. If that falls through parking along the road would be your next option just west of the Village parking lot along North Side Drive or Sentinel Drive, there are a few wide spots. Curry Village parking is typically partially full with people parking randomly just to make things exciting. Get there early and use the valley shuttles, bikes or walk through out the day.
I did find a Bus schedule from Crane Flat to Yosemite Village (see below).
