If you have tackled the other things on your list, you can likely address the CCV. If you pull the oil filter housing off, it will make the job a bit easier. Just be careful that you get all your hoses snapped properly. Some may be hard to get a good angle on them to properly connect them.
You might want to also go ahead and replace both the upper and lower intake boot and clean the ICV while you are in there. Also search and consider pulling the dipstick to replace the O-ring as well as clean out the double wall dipstick tube.
If you can do the work, you might as well do the job and get all the PITA items sorted once and for all.
Good luck and also check the 3rd link in my signature to make sure your coolant temps are really correct. Most of these cars should run between 90-93C consistently unless under heavy load when the thermostat heater kicks in and drops the temps.
