So far it sounds like you have the default installation settings for Coldfusion and the JVM and now that traffic is increasing your realizing the need to tune the JVM. This is a common occurrence since the default JVM settings are not meant for higher loads.
Coldfusion 7 does not have any monitoring tools. I have written a very simply monitoring tool for the company I work at. Currently I'm in the process of making this a standalone tool for anyone to use. Of course CF8 already has these tools built into the admin, but they are very heavy handed and can cause harm to a server under heavy load. Other options for CF7 monitoring are SeeFusion and Fusion Reactor. I've used both extensively at the company I work at and found both to do a great job each with pros and cons. I think both still have a free trial period. Actually, I'm sitting on my couch right now working on my monitoring tool. I'm trying to get it to work with BlueDragon, but I might be able to get a version out soon just for CF7/8.
