1. What time is the last bus from Taiyuan East Bus Station to Wutaishan?

1. As I know, the last bus departs at 18:30, and the trip takes 5.5 to 6.5 hours in usual.
2. The distance is about 117 miles (189km). You can charter a car to the mountain directly. It takes about 2.5 hours. The fare may be CNY600-700 for the single trip.
3. Yes, you can consider the Home Inn at No. 95, Wulongkou Street, Xinghualing District. It is about 0.6 mile to the west of the bus station. It costs CNY100-150 per night in usual time. Hope you like.
