Here's my small piece of advice since i know you have been given a lot already. I'm not a fan of the catch-can unless you have excess oil consumption that can't be solved any other way. The factory part has now lasted 20 years so doing it again will likely outlast the car.

Even if you're doing the CCV, you're going to want a smoke machine. Reason being, getting those pieces all together is pretty tricky, and I've done a least 6 of them and discovered a small leak every time. I now smoke-test the system prior to putting everything back together. You've opened up a TON of possible leak paths and if you're not familiar with the job there are plenty of small ways you can introduce a leak. You have to remove all the CCV parts, boots, the IAC, the oil dipstick tube, the throttle body, and depending on how you do it the intake boots. LOTS of places to make small mistake.

So, almost no matter what, a smoke tester when working on older cars is very, very helpful and I would say necessary when going this deep.

I know it's painful but having one takes out all the guesswork and insures the job is done right. And look at this way - by not paying someone for this job, you save the money to pay yourself back for the smoke machine. I have justified a lot of tool purchases by "paying myself back" for the money saved by DIY.
