ATT 24mbps to 45 mbps upgrade appointment 2/13/2013

I just got U-verse on 1/27/2013 u450, 24mbps internet and 2 phone lines. I LOVE IT. Online it showed my max internet speed available at 24. I called ATT yesterday and spoke to 2 people. It appears that I am eligible for 45mbps. I have an appointment for a tech to come out on Thursday 2/13/2013. I am just wondering how I can prep my place for this appointment. Before my Last appointment I planned out my network. I ran 2 to 3 Cat6 cables to each location 1 for data and 1 for tv and a third for RG and WAP where needed.

My current setup is 1 DVR, 3 STB, 1 Wireless STB, 1 Vap2500, 2 Netgear GS105 and 3 Netgear GS108 switches and a NVG589 RG.

Question - All of my Cat6 runs are in use. I still have some Cat6 in a box. Will the technician need another Cable or 2 to the NVG589 or am I good with a single Cat6 to the RG?

Thanks your knowledge and advice is appreciated.
