The danger of the CRTs is overblown, IMHO.  I used to be pretty wary of getting near the CRTs on them but a number of CRT/Analog board swaps in and I'm not dead yet.  Just make sure to avoid the red wire going into the CRT and you should be fine.  There are a bunch of threads on here about how to properly discharge the CRT and it's not as scary a process as it sounds, though it shouldn't be necessary to do so just to clean out the dust.

For one of the worst offenders (I couldn't see the components under all the dust!) I used a leaf blower and really kicked up a cloud (I wouldn't recommend that!), you'll be fine using a can of compressed air.
