After some digging (I really ought to dig first before posting in forums) I discovered it doesn't actually matter whether the high-res object's composed of dozens of different meshes or not, so long as the two objects are similar enough and the low-res is UV-mapped properly you can normal-map it. Fascinating.

It doesnt really matter if the high poly version consists of multiple objects.When you set a projection modifier(in 3dsmax this is) on the low poly(correctly UV mapped),and place the high poly in exactly the same position,adjust the cage,then it will catch the normal of the whole object.
I have done dozens of normals of multi objects,and i have to say,the projection modifier in 3dsmax,does a fabulous job at it..
-Create low poly version
-Create high poly version
(or the other way around,whatever suits you best)
-Be sure to center both objects to 0,0,0
-Properly uv-map the low poly version
-Place the high poly in the exact same position as the low poly version
-Add a Projection Modifier to the low poly version
-In the stack,click Cage
-Then pick a reference object,by clicking pick list(in this case the high poly version)
-Adjust the cage to fine tune it(click "shaded" for a better reference on what the cage is covering,and play around with the "percent" and "amount" settings
-Then hit render to texture,and tick projection mapping Enabled.
-On the mapping coordinates section be sure you use the EXISTING Channel!(because you dont want Max to screw up your uv's)
-Then add a normalsmap in the output dialog,choose bump as a taget map slot
and be sure to tick "Output into Normalbump" in the" Element unique settings"
-There ya go,...Done,render to texture ,and there's your normalmap.
Oh and add lights to your discretion,...

Ooh. Thank you for the detailed reply! That informative even beyond my inquiries. :) I got my initial impressions of normal mapping from my experiences with Zbrush, so that's where I got mixed up on the whole process. I'll start digging around 3DS Max for the normal mapping stuff!

You know, I've actually heard good things about it. I may just do that. :)
