100 amp sub panel ground wire size
2. YES you can use #4 Al as your ground. Your 1AWG Al is good for a 100 AMP feeder (actually 110). From NEC 250.122 this requires an #8 CU or #6 Al ground wire as a minimum (or 6CU and 4 Al if you are really running a 110Amp Feeder). As a reminder, your feeder will be 4 wires, the two hots and the neutral will be #1AL (unless you've de-rated ...If you can accomplish this with only the addition sub-sub-panel and move enough house circuits to it, that will suffice. Again, the addition sub-sub has its own feed breaker in the main-sub. The wire between the two decides the size of the feed breaker (and this is picked out of the tables for branch circuits, 310.16, not for service drops).
