[Jenn Lindsay] “Would it be a terrible idea to update my iMac version to 10.3 while I’ve got some active projects?

There is always some risk in upgrades, and 10.3.x is a major upgrade. Also the UI has some changes so it will take a day or so to become accustomed to that. I was forced to upgrade a 5 TB project to 10.3.x because of a plugin rendering bug in 10.2.x. The upgrade mostly went OK but I later hit a crash on import problem that took a while to figure out. Overall I like 10.3.x better.
If you are doing collaborative work with someone on 10.3.x, it may be worth upgrading — you’ll have to make that decision. Part of the upgrade process is evaluating what plugins you use and making sure those are updated and work properly in 10.3.x.
10.3.x has some nice features, also a few frustrating minor issues like the Browser layout reverting to the default each time FCPX is restarted. In general there are lots of useful improvements.
If you save a copy of your libraries and your current FCPX application, it is relatively straightforward to roll back, provided you don’t need to preserve work done on 10.3x.
