What is the significance of the last value?

It relates to the amount of energy stored in the battery expressed as
the number of mA it can supply for one hour (although it is actually
measured at a 5 or 10 hour discharge rate as using a one hour rate
would be misleading).

Rather simplistically 650mA battery can supply 65mA for 10 hours or
130mA for 5 hours.

Could a 1000mAh be used instead.

Yes

Would that increase the 'storage' period?

If by that you mean would it increase the use you got out of the
phone between charges then yes it would.
