I can tell you what I would charge. $145 for the plug replacement, and around $135 on the filter change. So their prices are probably a little higher due to shop rates.
Now, the normal time for service on your plugs is every 100k miles. There is no listed time for replacement for your fuel filter. Usually if it works good, wait until it causes problems.
