Make entry as easy as possible text entry for times & dates - with a tooltip calendar, (unnecessary pop-up lists are a pain for anything when entering bunches of records.) Consider using chekboxes and radio lists for selection over popuplists sometimes they provide visual cues easier then reading or expanding a popup.

Reduce complex multi-table entry forms to one screen, same with displaying data... Make it so in reports where you might need to correct entry staff can click right to record edit instead of having to back out, etc.

Try to make every bit of data collected usable, don't just have a "office hours" field have a schedule entry so you can draw on the data - down the road someone will say, I saw you collect X, can we use that to do Y? Be prepared to say "no problem."
