Here is a fleet I am considering for upcoming tournaments. I have 6 activations and 9 deployments. Please advise.

Dodonna MSU
393/400

• CR-90A ( 44 points)
  + General Dodonna ( 20 points) ← Garm or Cracken could fit here instead. I guess I'm not 100% sold on Dodonna.
  + TRC ( 7 points)
  + Jaina's Light ( 2 points)
  ship total = 73 points
• CR-90A ( 44 points)
  + TRC ( 7 points)
  ship total = 51 points
• Nebulon-B Support Refit ( 51 points)
  + Skilled First Officer ( 1 point)
  + QBT ( 5 points)
  + Salvation ( 7 points)
  ship total = 64 points
• Hammerhead Torpedo Corvette ( 36 points)
  + External Racks ( 3 points)
  + TFA ( 3 points)
  ship total = 42 points
• Hammerhead Torpedo Corvette ( 36 points)
  + External Racks ( 3 points)
  + TFA ( 3 points) ← I chose TFA instead of TFO because I want to make sure that they live long enough to drop their racks.
  ship total = 42 points
• GR-75 Medium Transports ( 18 points)
  + Toryn Farr ( 7 points)
  + Bright Hope ( 2 points)
  ship total = 27 points
• Hera Syndula ( 28 points)
• Shara Bey ( 17 points)
• Tycho Celchu ( 16 points)
• 3x A-Wings ( 33 points) ← My thought here is that the Bright Hope can activate these three A-Wings, and Hera can give the aces Rogue.
  squadrons total = 94 points

Objectives: Most Wanted, Contested Outpost, Solar Corona

Don't go Garm with this. On top of being a bottom-tier commander in general, he's usually best utilized by larger ships. Cracken would be alright, but Dodonna is very good and I'd stick with him if I were you.

I think you're a little over-invested in squadron defense. Your wing is nice in that it's fairly flexible and can support in ship combat too, but in my experience A-wings just get mowed down by flak so fast. Your mileage may vary, I just see 94 points of primary antisquadron that could be a liability. That said, you do need a strong defense, as your ships aren't going to be particularly resilient to squadrons so you need to inflict some damage in the squadron fight.

I really like that Salvation build. I've only tried it once and completely botched it, but it's a cool build, especially with Toryn in the list.

I don't think Contested Outpost is ideal for you. Consider switching it up for Capture the VIP, Hyperspace Assault, or Planetary Ion Cannon. None are super ideal without Strategic or any particular way to leverage them, but I think CO is too big a liability for a highly mobile fleet like this.

From my experience, TFA works better with 3+ HH, because balancing 1dmg/turn only doesn't worth it.

Did you choose Dodonna only for points purpose? Because in your list you do not really max his potential (no Bombers crit hunters for instance). Cracken or even Mon Mothma may be better choices for you. Or even Leia, but she is very expensive. Garm is no good for you, keep him for fleets with 2+ command ships, otherwise his token generation is useless.

I play Salvation with Spinal Armament to max the chance to have the right face of die with this title, this + CF of course.

Actually, your gr75 is able to activate 2 Awings, not 3. For that you'll need General Leia or Expanded Hangar.

Id Stick to Cracken. Garm isnt really helping, Trc and Dodonna is Two different approaches. Also agree on tfa, having 3+ and a pelta with stm brings the Max out of them. But with Small numbers and the Fact that They dont have ordenance experts makes me suggest to go for tfo, youll be Better with that reroll, and cracken Will give them that extra tankiness. Fighters: Yt-2400. Try them.

Mothma could also really help boosting the survivability if this list.
