Yeah, the Jaguars are a royal mess. Here is what I've been able to glean from canon (and Sarna.net):

Totals:
Galaxies: 12 (8 named; 4 unnamed)
Clusters: 65 (2 Jaguar Guards, 1 Aggressor, 5 Assault, 2 Attack, 6 Battle, 1 Jaguar Grenadiers, 2 Jaguar Cavaliers, 3 Jaguar Combat, 5 Jaguar Dragoons, 11 Jaguar Regulars, 5 Striker, 1 Freebirth, 4 Solahma, and 17 Garrison)
We seem to be missing a few Galaxies . . . unless the Jaguars used more than five Clusters per Galaxy, which I don't have ANY evidence for. And the hodge-podge of differing Cluster types just boggles the mind. Still, just using references from canon, that gives the Jags more strength than even the Ghost Bears above.
Which is something.
To your second point, I think it was said (in Invading Clans, maybe?) that the ilKhan (Showers) forbade Trials against the holdings of the Invading Clans during Revival. I know I read that somewhere . . . I think. LOL
