You are probably already aware of this but be aware of your Autocad 0,0 in relation to Revit's Project survey point and shared co-ordinates (if you are going to use them. Try and get a survey point somewhere on the site rather than thousands of feet/metres away in any direction. Also try and set a common project base point between your self and any other disciplines working in Revit/3D with you.
I would also set my project units to have a high precision for lenghts and angles as I found that Architect's appear unable to draw walls perpendicular or parallel even though there are tools in Autocad. It would be worth spending a little extra time up front making sure that walls are square (unless design ontherwise) by doing a few check angles otherwise later on Revit will snap/align itself to the objects and you will for ever get the warning of "Element is slighlty off axis and may cause errors" and then the knock on is fittings not showing correctly, systems not connecting, etc. You know drill with Revit and its sensitivity.
This is something I spent ages trying to rectify on a project as the architect had minutely different grids between floors and the knock on effect was time consuming and boring to fix!! we are talking 0.0004 of a degree but enough to make Revit have a tantrum!!
Hopefully not teaching you to suck eggs but trying to save you a nightmare later on.
