Hi Cameron,
I'm not so sure that you'd find a tutorial for best practices. Most of my work at this time has been housing whether its single detached homes or multi-residential buildings. I'm barely two years into using VW and I'm slowly figuring out how to best use the program and get useful information from it. One of the first things was doors and windows and producing a meaningful schedule for each by using worksheets. Since then I've been looking at making take-off worksheets to get accurate measurements of the different types of materials being used. So I use component based walls, floors and the like. That being said making/using 3D objects in your model is cool but you'd want it to pay off in time. Using walls, floors , roofs and the like can get your cross sections up fairly quickly as well as some details but I find I still use a lot of 2D objects to fill in the gaps. Modelling out joists, studs (framing in general) can be a lot of work and would only be beneficial to me if I can get more info from them other than making details and sections easier/accurate.
Do you have access to VSS or Vectorworks Service Select? If so you'd find a large number of tutorials, how to's and the like that may be of some use to you.
Cheers!
P.S. Had a quick look at your website (nice work by the way) and with some further thought I'd add that ya for you modelling out parts may be of an advantage especially if you use them to illustrate to your clients what the final product or feature may look like. There are plenty of visual clients out there that love this kind of presentation.
