Satellite Placement? Should I use both that came with Router?

Daisy chain enabled should let the system determine the best set up, but in your situation the daisy chain most probably would not be initiated. Check on the backhaul conditon on the web gui and if it is good you should be good.

I suggest download something like WiFi Analyzer. You can then check the various signal strengths at approximtely five and ten feet from the router and then satellites as your phone switches. This will give you a comparative assesment for placement.

The RBW30s should be a minimum of about 30' from the router, but if you are going through a floor and walls you may be fine with #2, though it is a bit close to the router as described.
