Record 6 installation preps

I'll be getting the Record 6 and 3 clients installed soon.  I prefer to do most of the in-wall cables myself prior to the installer arriving.  Do I need to run a single RG6 cable from each device to the point of entry, where the installer will install a splitter, or are additional splitters downstream OK?

 I have some instances where TV's are close to each other, for instance my living room and kitchen TV's are on opposite sides of a wall.  Currently, there is a single coax run from the point of entry splitter to a 2-way splitter in the wall, then a short run to each cable box.  Is this topography OK with the Record 6 system?
