Priortizing Targets

The web site shows 221 potential targets for observation.  I checked about ten of them and very few observations have been made since the YSO forum started.  Do you have a priority list?  What frequency is appropriate?  Are multi-band observations valuable or is a single filter preferred?  I know from observing HBC 722 and VSX J2051+44 that these objects tend to be very cool, so if we use a single filter is it better to use I or R?  The two I've been oberserving are much brighter at these wavelengths enabling better measurements and allowing me to use a smaller scope for observations.

Also, is there a good text or set of introductory articles about YSO's beyone what is discussed on the web site?  I think many of us would like to know more about them, and also understand how photometric measuarements can be utilized to better understand these objects.  In particular, are the measurements of value "stand alone" or do they need to be coordinated with professional spectral observations?

Thanks.
