Replacing the binary is sufficient if the only change you make is the
number of filedescriptors or other changes which only affects the binary.

As Squid is almost self-contained (except for icons and error messages)
within the single binary there is little else required, but if you change
to use external DNS helper (--disable-internal-dns) then you need to
remember to install the dnsserver binary as well.

The interfaces to different helpers such as authentication or external_acl
helpers is neutral to a recompile. There is no need to have helpers
replaced only because you recompile Squid. There is however sometimes a
dependency on the Squid version as the interface sometimes changes slighty
(auth helpers for Squid-2.4 won't work 100% with Squid-2.5 or later)
