Connect 3+ routers in Sequence

Hi,

I'm trying to figure out how to setup 3+ routers in sequence, and the settings required for each router, so I can run them down a long corridor.

The Router connected to the internet is a Draytek Vigor 2800.
1 IP 192.168.1.1
Subnet: 255.255.255.0
DHCP IP range: 192.168.1.50 - 192.168.1.150

I purchased 2x TP-Link TL-MR3420
I've set IP's on both of these to
2 IP: 192.168.1.2
3 IP: 192.168.1.3
Subnets are also the same


Questions:
A: Am I right to Disable DHCP for routers 2, and 3 as IP addresses for each computer connecting to the network will be assigned by router 1?

B: I want to connect them in sequence 1-> 2-> 3, Is it correct to connect them via the Lan ports, so
Router 1, Lan Port 1
TO
Router 2, Lan Port 1
Then
Router 2, Lan Port 2
TO
Router 3, Lan Port 1

Is That correct

C: Does it matter what I call the networks, or do they all need to have the same name?

D: is there any other setting I've missed out on?

TY
