As far as connection sequence, follow the recommendations of your inverter manufacturer for connecting it to and disconnecting it from the batteries.
However, before you connect the inverter, the last connection you should make on the battery bank is the connection from the batteries to "ground" (vehicle chassis). This is also the first connection you should break before any maintenance on the batteries, after first disconnecting the inverter per its manufacturer's instructions.
Also, since it has not been mentioned here yet, I will make explicit something that is shown in Craig's (Gumpy's) diagram: connect the load to the positive of one string, and connect the ground to the negative of the other string. You can think of this as "connecting on the diagonal." This will keep the load and charge profiles even across both strings.
