Question regarding ONT connection via Ethernet and Cable cards

Question

Hi,
We recently upgraded to Fios Quation 150Mbps/65  plan. We are not getting the advertised speeds (we only get like 5mbps upload) so verizon is sending a tech to switch the ONT connection from coax to ethernet.
I have 2 questions regarding this new setup:
1. If the ONT communicates with the Fios Actiontect router via ethernet instead of coax from now on, How will the set top boxes and Tivo-esque cable card powered device I currently have connected to coax, talk to the verizon system from now on, if coax is taken out of the equation? Will fios signal still flow through the internal coax wiring of the house? And moreover, I was under the impression that coax was the way set top boxes communicated and derived independent ip addresses from the Fios router, for on deman purposes and what not. How will this work from now on?
Quiestion 2.
Right next to the wall where the ONT sits, theres's a basement office where we have a PC that connects to the Fios system  via an Actiontect MoCa adapter (ECB2500C) which I assume derives it internet connection from the Fios Actiontec router which sits upstairs in the living room. 
Again, with the Coax about to be disabled next Friday in favor of ethernet connection from the ONT, I assume this PC will be left without internet because of the lack of internet signal in the coax? Is this correct? 
Question 2.5 If my above assumption is correct, since this office is right on the other side of the wall where the ONT sits outside the house, would it be possible to run an ethernet wire through the wall that connects straight from the ONT to an ethernet switch inside the office, from which I would derive a connection for this basement PC (properly firewalled of course) and then, from said switch, continue running the ethernet wire that would ultimately reach the Actiontec Fios router upstairs from which the rest of the house derives it's internet?  and would this setup affect in any way the propper functioning of the cable boxes in the house?
I'd appreciate your input and any help you can provide so I can have a ballpark idea of what to tell the Fios guy to do when he comes on Friday.
Cheers.

Answer 1

It's not valid to have two devices connected to the ONT, PC and VZ Router.  Must be a single device. The ONT locks onto the MAC Address of the first device it sees. Since you have TV you should have the VZ router as the internet facing router.
Other options:
1.  Have the VZ Router located next to the PC in the basement and then use Wireless for all other PC's.
2.  Have the VZ Router located next to the PC in the basement but run one wire upstairs and connect a switch where other PCs and devices can connect via a wire.
Hope that helps.
