I ran the following tonight against Han and Chewie,

T/B •Captain Jonus (22pts) adv. Proton Torpedoes (6pts)

2-T/B Scimitar Squadron Pilot (16pts) with Cluster Missiles (4pts), Flechette Torpedoes (2pts)

LS Omicron Group Pilot (21pts) Heavy Laser Cannon (7pts)

It did very well but I was wondering if I should change this up any?

Also when using the Cluster Missiles - Attack (target lock): Spend your target lock and discard this card to perform this attack twice.

Does Jonus effect work on both attacks?

Yes, he buffs both cluster attacks.

Yes, he buffs both cluster attacks.

Outstanding.

I'm not a big fan of Adv. Proton Torpendo. For 6 points maybe i replace them with other upgrade/missile. Jonus has EPT, what about Determination (keep more alive) or Swarm Tactics (giving other ship PS6)?

Yes Jonus affect both attak with Cluster.
