Hey Tahoe 97, this is not related to your question, but do you live in tahoe? If so where do you ride? I live by Sacramento and I'm looking for some good riding places in the mountains.

I don't think that your new air filter and vents will hurt any thing but it will give it more air flow threw the engine. With that you will have to rejet the carb, don't worry rejeting is no big deal and the jets are only $3-5 each. If you are going to get a pipe real soon then wait and rejet then. If a pipe is a way off then I would get it rejetted right away. You will run it lean on the air to fuel ratio which you run the risk of burning up your engine!
As far a pipe, they all are pretty good. I have a FMF and they have awsome tech support. So if you get one of their pipes give them a call and they will tell you what to jet it at (or at least real close). Get yourself a service manual, it is worth it weight in gold. It will show you how to get to the jets on the bottom of the carb.

Air box vents well defintely help air flow. Two pipes I would recommend are the Yoshimura and WB s bend slip ons. They both are high quality and worth the money. They run between 220 and 250 dollars. Jetting is a necessity whether or not you get a pipe, if you install the air box vents. FMF makes an ok pipe, but there four stroke pipes just aren't as good as their two stroke department. Hope this helps a little.
