I'd upgrade to a 24V Tm, probably a MK 80# minimum. I have the AP & have yet to get 1 whole day with it functioning properly. This year I upgraded to a Co-Pilot addon. In my opinion, the Auto Pilot is not worth the money. I've had mine re-calibrated twice last season by a factory warranty rep & it still never worked right. The universal transducer on the other hand is wonderful & a very good option.
Get a spare tire mount, but if they are selling you a Tracker bias ply tire, pass & go with a Goodyear Marathon, as you'll be upgrading to those on the trailer in a short while anyways.
Boat Cover, I bought a Tracker labeled cover to fit my Targa & after only 2 road trips (short trips, maybe 300 miles total for both), it started to fray & tear. You will want a cover, but think about a custom made cover by a local boat cover shop made to exactly fit your boat.
Upgrade locator(s) if within budget. You want a color unit on the console, & a bow mounted one also if you will be usually fishing from the front casting deck.
Height adjustable seat pedestals for the front & rear decks are nice if you plan long days where leg fatigue becomes an issue. The factory seat pedestals are way too short (at least for me, I'm 6'2").
Boat Buckles in place of the factory transon tie downs.
KeelShield is a must in my book also. Aluminum or not, you still will take comfort knowing it's under there each & every time you beach the boat. My dealer thought I was nuts wanting one on my Targa, but I had to remind him "who's money it was".
Ram Mount rod holders. The Ram 2000's are nice, I have 6 of them. I fish walleyes a lot where trolling is a must do, but even if your going after bass or pan fish, eventually, you'll want to set down a rod to take a break, or rig a 2nd rod, etc. Comfort is knowing if a Musky should take the bait while the rod is unattended on the deck, it can't pull the entire rod in because it's in a quality rod holder.
If you getting a 90 Opti, you most likely will want a Stanless prop to properly utilize all the raw power you will have at your beckon.
How's that for an expensive upgrade list on short notice to think about it?.....LOL
