Running the wire is the key element right now. If you take good notes (measurements from walls, ceilings, etc) of where your wire ends up and take pictures, you don't have to worry about terminating all the wire right now. It can literally live behind the wall until it is needed. Then you can cut the wall and put in the face plate at that time.
Again, I would be much more concerned about your wiring plan. What wires are you running to what places and for what reasons?
How many RG-6, mini coax, and Cat5e/6 wires are you running to each TV?
How many/what cables are you running to source equipment locations (like DVD players, console games, etc)
How many HDMI (if any) cables do you need to run?
Where are your speakers going to be located and where will the source equipment be located?
What size speaker wire do you need?
Do you want to wire for potential keypads in the future for alarm and/or audio zones (ie volume controls)
How many Cat5e/6 wires are you running to computer and printer locations? Wireless Access Points? Router location, etc, etc, etc
What about alarm wiring? If the walls are open, there is no better time to wire for door and window sensors, motion detectors, glass breaks, smoke detectors, etc. Yes you can generally get wireless versions of all these sensors, but they are 15x the cost of hardwired, more obtrusive visually (bigger because of the battery packs), and less reliable than hardwired sensors.
What about a lighting system? Doing it now or in the future? What 110v wiring do you need (ie a neutral wire is requried on a lot of "wireless lighting" systems)? What low voltage wiring do you need if you are not going with a "wireless lighting" solution?
What about HVAC control
CCTV in the future? Analog or digital? Wire for both? Don't forget power (POE or 12v line usually)
Etc, etc, etc.
As far as terminating wires, I do things differently depending on the type of wires. Obviously Cat5e/6 wires are terminated in their appropiate RJ-45 connectors. I like to connect speaker wires directly without using face plates. Same with HMDI cables - direct connections work better. For RGA (via mini-coax wire in my house) and RG-6 coax, I do use wall plates most of the time to make connecting source equipment easier. But I have also been known to direct connect without wall plates too! When I direct connect, I like the pass through plates that you linked too. I don't use speaker plates, so I wouldn't use the speaker plate you linked to. But I do use the interchangeable RJ-45 , RG-6, and RCA keystone plates when I want to use plates. Something like this
