Suzhou Sightseeing

I will be arriving in the city from Shanghai in the morning. My plan is this:
1> Visit Han Shan Temple
2> Visit Tiger Hill
3> Visit The Humble Administrator's Garden

I can read and speak Chinese.

My main concern is this, how do I get from sight to sight? Are the taxis relatively easy to flag?

I only have a day trip there and don't really want to mess around with the bus networks but if I have to, I am wondering if there is a website where I can find out how to get from the sights via bus.

Any advice appreciated! Many thanks!
