Some more good advice from my dive through the snarkives:
Novel queries really don't need biographical information. Or, you don't have to be a lawyer to write about them. In fact it might be better if you weren't.
From an agent's point of view, the value of a magazine sale isn't in the size of the check, or even in getting a check. It's in the credential that says a reputable editor thinks your stuff is worth printing-emphasis on reputable. The magazine has to have a seriously respected name if it doesn't pay pro rates.
There are a very small number of reasons that are acceptable for bothering an agent who is looking over your work.
Pre-blurbing. A bad idea that should be stepped on vigorously.
Another entertaining round of follow the directions when subbing to an agent, along with some suggestions for what not to put in a query.
