Some points to consider:

-if you enjoy working on your bike yourself or
-and/oryou want to work on your own bike to save money, then
many of these specialized tools will pay for themselves versus taking the bike into the shop for the same service even just 2 times.

OTOH,:
-if you don't like turning wreches
-and you'd rather spend a few bucks and have a professional take care of it for you,

Then the LBS is (hopefully) there for you. Get yourself a decent multi-tool, a good floor pump, and some tire levers. Let the shop handle the rest for you.
