I think you can Edit your first post. to change the topic name (hit the Green Death star button)
For this missions you should Identify all the Trasnports, ans support vessals first before you ID the Star Destroyer.. save that for last.
ID the Star Destroyer, and you should here, or read about the Probes lauvhing.. dont go after them right away, because they would be in the Engine wash, but wait a while, and tangle with a few of the TIES
NOTE: try to destroy all but 1 of Each FG, it will reduce the # that are going after you, and you wont have to worry about new waves.
You can take some out with missilse, but i would worry about the TIEs so much since you should be Diverting all alser energy to the engines so you can go fast and be lest likely to be hit by enemy fire.
I typically crusie around with Lasers at -2, and shilds at even or +1
