Boomer,
The ratings on muni's are the same as conventional bonds i.e. a triple A rating is the highest possible rating. The ratings are based on the credit quality of the issuer. Most brokerages have a bond desk (I use Schwab). They can advise you about individual issues. There is a primary and a secondary market for muni's just like regular bonds. I also prefer to buy individual issues rather than funds because I can hold them to maturity without worrying about interest rate changes that affect funds. Hope this helps.
