I've always been interested in working with the FDS's FM capabilities, but I don't really know how to get the right J and I values, and I can't find anything online, on the wiki, or in any threads here. So, is there any way to easily get those values?

It's hex. Having effects JAB and ICD will give you a frequency of ABCD in hex. Find whatever source of [url=http://www.phy.mtu.edu/~suits/notefreqs.html]note names to hertz you want and then open up calc (scientific mode (why would you ever not be in scientific mode?))if you're bad at hex.
For example, middle C is 261.63hz which rounds to 262 decimal which is 107 hex. So use effects J01 and I07 to get that frequency rate. It should be noted that the highest value the FDS can do is J0F IFF, which is why I usually always explain it as J0x Ixx.
It's still up to you to find a good mod wave (the default sine usually is good) and find a good mod depth either by leaving it constant in the FDS instrument or by using Hxx, which has a highest value of H3F
You should definitely wait until the FDS emulation is corrected. I've already experienced the hard way how unpredictable it is even for different emulators. My guitar instrument sounded like shit on anything but Famitracker.
Were there any FDS games that used the FM in music for more than just hardware vibrato? As far as I remember Metroid used it for its sound effects, at least that's something to help study its behavior.
I think the golf games used the modulator, but only very little. I own Golf - US Course, but it only uses it [url=http://youtu.be/1s7H82yFNf8?t=14s]once on the title screen.
The melody in Shin Onigashima uses the FM channel, for the most part to emulate a shakuhachi. Fun fact: the soundtrack is written by the one and only Koji Kondo.
