If you are not having problems with a high idle, I would leave the idle air hoses alone.

There are two short pieces of hose that connect to the idle air valve, and a breather hose that connects to the left valve cover. They need to be moved to get to the left front injectors, so you might want to replace them if they have cracks.

I am hard-pressed to come up with anything else that you would replace as a matter of course along with the injectors and seals. It's not like you gain access to stuff in the course of the job.

A 14mm crowfoot and a set of 6" hex bit sockets (KD Tools) will make the job a lot easier.
