Check out Appendix 2 of the COMNET Modeling Guidelines and Procedures. It's an Excel spreadsheet with a list of plug loads and other internal load assumptions for a range of building types. Like with any resource, use judgment regarding whether the numbers make sense for your case. But it's a good place to start. See http://www.comnet.org/mgp/content/appendices?purpose=0.
And COMNET Appendix C includes a corresponding set of schedules.

I find chapter 18 of the ASHRAE Fundamentals to have some useful tables, especially for offices.
ASHRAE's Advanced Energy Design Guides are a good source of load assumptions for several building types, and they include both standard efficiency and high efficiency values in some cases.
If you're interested in internal load schedules, then check out ASHRAE research project 1093-RP. It provides hourly profiles for several building types based on some measured values. Many "default" schedules do not include realistic nighttime plug load values.
