tokyo city has very good transportation system.
it may be a little far to walk (but if u dont mind, u can actually walk.) from one place to another as u've mentioned above, but the subway system in tokyo is one of the most convenient ones of all. no worries, their subway stations' exits are easily found. and they take u to all the places u mentioned. yes indeed roppongi is a higher end of entertainment district while shinjuku is more for the hippier funkier young crowds.
so dont worry. its close enough. but still hands down for the subway in tokyo. because of it, much walking arent that required! enjoy ur trip.
