60k Maintenance dealer quote breakdown

Hi All,
This is my first post.
Time to send my 2005 Elantra GLS for its 60k service.
Here is the breakdown of my local dealer's quote:

timing belt & drive belts $399.99
fuel injector svc $106.99 [why do I need this? Not mentioned in my Hyundai maintenance log book]
trans svc $84.99
coolant svc $74.99 [does it cost that much to flush the coolant?]
power steering flush $85.99 (if needed)
rotate & balance $39.99 [don't need it, comes with tire purchase]
air filter $13.12 [do it myself]
pcv valve $38.00 [pcv valve is cheap on rockauto.com. I feel like doing this myself but am scared of breaking something]
throttle body svc $39.99 [what is this? Again, not mentioned in the maintenance log]
spark plugs & wires $125.00 [looks like a rip-off to me. Will buy spark plugs and try to change them myself]
clean, lube, adjust rear brakes $44.99
(same for front if needed)
a/c system check $41.25


My comments are in [...]
All advice/comments are welcome!
One question:
Is a spark plug cable = spark plug wire?
My Elantra is a 2.0 CVVT
Do I have to change my spark plug wires?
On rockauto.com a set of 4 spark plug wires cost any where from ～$30 to
~$40. Looks pricey to me for a bunch of wires...
Any brand recommendation is very welcome.

I live in the East Stroudsburg area in PA right next to NJ not far from I-80.
Will be very grateful for any recommendation for a good mechanic in the area who can do the job for somewhat less $$$!

Thanks!

This is to follow up my previous post. What are the tools that I need to
replace the spark plugs and the PCV valve?

I am really new this. I should be able to buy them at Sears right?
