We will be in HK from the 24th-28th and I need some help :)

(1) We would like to experience the Open-TOp City TOurs. How do we get to Golden Bauhinia Square (which is the starting point of the tour) from Bridal Tea House Hotel at Li Tak St., Tai Kok Tsui?
(2) From the same hotel, how do we go to St. Mary's Church?
(3) Are there HK maps and travel guides found at the HK International Airport or in hotels?

Thank you for your help.
