To make this easier I am interlineating my answers below in Red
Please keep in mind the lower you discharge your batteries the shorter life they will have. This is especially true for flooded batteries.

I've got the Xantrax Freedom 2012 Inverter/Charger. I've never had an inverter prior to this M/H. When I bought the coach it had 4 - 230 amp hr AGM batteries. I've not messed with any settings on it yet. I had to buy 4 new batteries today. I bought Trojan T-105 and they are 225 amp hr.
I'm going to install them tomorrow and do whatever I need to at the inverter display panel. I don't really know what to do. I understand I need to reprogram it for the new batteries. Hopefully, I can follow along in the Owners Guide. Here's what I have found I'm supposed to do.
1. Battery Type: It should set to "Flooded". I am assuming it is set to AGM now.
Yes
2. Battery Capacity: I've got 4 at 225 amp hours so should I set it to 900 amp hours which is the total of the 4 new batteries? According to the Owners Guide, the default is 250 Ah but is configurable between 50 and 2000 Ah and I don't know the increments. OR is it asking for the Ah of the individual batteries instead of the total of the whole bank?
No, you have a series parallel configuration which means you add the capacity of two sets. This means you get 2 x 225 total. So in your case you AMP hour capacity. Please understand you can only use 1/2 of that capacity because lead acid batteries lifetime is dramatically shortened if you discharge them more than 50% depth of discharge.
3. Max Chg Rate; I assume this should be set at 100% but is also configurable between 10% and 100%
100% is fine
4. Charge Cycle: I should set it to 3 Stage charging.
Yes
5. ReCharge Volts: Default is 12.5 but is configurable between 11 and 13.5 volts.
12.5 VDC is fine.
6. AC1 Breaker: Default is 30 but is configurable between 5A and 30A. I'm not sure what this means. I am normally plugged into 50 Amp circuit. Every now and then, to 30 Amp and seldom if ever to 20 Amp. Would this mean I need to change it to a lower value if I'm plugged into a 20 amp circuit or should it just be left on the default 30A?
This tells the inverter / charger if you are plugged into a 15, 20, 30, or 50 Amp circuit. Set it as appropriate.
7. Low Batt Cut Out: Default is 10.5V. It is apparently configurable for these settings: 10.5V 10.0V 12.0V 21.0V 20.0V 24.0V
I would use 12.1.
Like I said, I do have the manual but it is apparently assuming I know more than I do. I didn't find any help on YouTube either. Am I missing anything else I need to do or do you have any suggestions?
