I & my family from Hong Kong will arrive Osaka at Kansai int'l Airport, go straight to Kyoto where we'll stay for a few days, then go back to Osaka. Please help:

(1) how do we go from Kansai Int'l Airport to Kyoto (Hotel Nikko Princess Kyoto), by airport bus or JR (which route?)?
(2) assume can take JR back to Osaka?
(3) does any JR Pass cover transportation between Osaka and Kyoto?
(4) if yes, which JR Pass should we buy?

Appreciate if any additional useful information can be provided. Many thanks.
