Which of the following is true, if any?

1. Once you switch to battery power, you should stay on it until the % left is = or less than 10%. Then go on AC power till !00 %.

Every battery has a limited number of full power cycles it can perform. Charging before you have taken the battery down to about 10%. Constant recharging reduces the overall life of it.

2. Keep the battery as close to 100% as possible and only use it when you have no AC. Cycling the battery down lowers overall life.

Which is correct and if neither what is correct in general for overall battery life?

Li Ion batteries have a limited number of charge cycles. To maximize battery lifespan:

Completely drain and charge the battery, no partial drains or charges
If your not using the battery for a prolonged period store it with a 40% charge
Once the battery is charged remove it from the laptop
Keep the battery out of heat

So a take off is which is more important for lifespan as well as time on battery, the Ah or number of cells?

Capacity (Ah) and number of cells don't have anything to do with lifespan. More cells can add capacity, voltage or both. All Li Ion cells begin deteriorating from the moment they're manufactured. The only difference is the specific type of chemistry used. Only get a higher capacity if you need it.

The more Ah and or cells, the longer the cycle till charging needed. The longer the cycle, the less cycles used on a per week basis. Thus a longer life cycle- No?

The problem with this is that the battery tends to be left in a less than ideal state, either a low charge or partially discharged and charged more often. Although if you can avoid doing this then more capacity may work for you.
