Re: Merging levels from multiple files
For example, is it better to always draw the walls of each level separately, even if the outside walls always span both floors, or if you have the occasional room with 2-story interior walls, such as for a 2-story entryway?
Use walls only for the floor where they are. The reason is simple: if you texture the walls for a room you don't want to span that over multiple floors but keep it to the room where you set the wall texture. It's easy to create walls above each other: just copy them from one level to the next above and they will look on the outside as a single wall. With a 2-story entryway you could use higher walls but that's an exception to the rule. You probably want to use walls per levels anyway for this since the other side of the wall is most likely for another room and you want to keep room textures for that room.

Similarly, are there issues to using negative heights, say if you have a garage that is a few feet lower than the main floor of a house? (i.e. you need 3-4 steps to get from the garage to the first floor because of the grade of the lot, etc.)
No issues, it's just that the level has a negative elevation value, that's all. The walls and floor you handle just like any other level. You might want to set a different height for the negative level if you want to equalize the ceiling with the ground floor level but that depends on your design.
