Too many routes and options among too many transportation choices to make a very comprehensive site with up-to-date info. The one closest is HK Goverment's app called "HKe Transport", which has point to point options and fare info, but I can often find better routings.

Usually, for fare and timetables, I use each company's app - KMB, Citybus/NWFF, and MTR. And the websites of the ferry companies and New Lantao Bus.

BTW, HK Tramway is $2.3; Star Ferry is $2-$3.4 depends on upper/lower and weekdays/Holidays.

You're right about the tourist pass. You have up to 4 days to use the pass portion.
