Do you have an atlas or a planetarium program? (Cartes Du Ceil and Stellarium are very good free examples)
Many people start by looking for the Messier list objects, but there are many more to see, especially with a 10"er
Have a look in the Observational Astronomy subforum here on IIS; also you could do a search for threads by "glenc" which generally contain many many lists of objects to observe - normally sorted by object type, magnitude, whatever..
*EDIT* heres the search results I mentioned
