general tune up

i am about to do a general tune up on my 87 dx. I am wondering if i should check anything else besides the following...

change oil and filter
change spark plugs
replace fuel filters
check coolant
check ps fluid
check brake fluid
check air filter

pvc valve, air filter

check cv joints....ball joints....any oil spills....might want to clean up engine bay after....makes the car look better....

Plug Wires, Check your exhaust for leaks/holes too.

valve lash, that sea foam people talk about? flush coolant, dizzy, cap, just small things would make a good change
