I agree with the above posts buy 2 of whatever you get, if you are buying spoons you can try and risk getting the same color in two sizes as your "2" but that's just if you are getting down to the wire $400 goes fast.
The extra downrigger stuff is an absolute MUST, get an extra BELT, at least 1 if not 2 extra cannon balls, all the equipment you need to re-rig your rigger should you loose all the gear on one side, or heaven forbid both!
Bring an assortment of 4, 5, 6" spoons Tomic and Coyotee's would be my choice but it also depends where exactly you fish.
For Coyote's

Live Image Green
Cop Car
Mongoose
if on the budget get them in 4" and 6" models (1 of each of if you have the money 2 each)
Tomics has lots of wicked spoons again if I could only have a couple
232, 632, 512, 400, 500, 727, 530uv, 639bd in the 5-6" sizes
Hootchies and Flashers
If I could only have a few colours
Army Truck
Pistachio
Purple Haze
Jack Smith
- these seem to work most places but find out local colours to the spot you are going cause the hot colour can change pretty quick.
Tomic Plugs in larger sizes in the middle of the summer 6-7" or smaller in the beginning of the year 4-5" (search the forum "tomic plugs" great posts on where and when and how to use what).
I like Hot Shot flashers but obviously most flashers work, Green with silver, purple haze, red/orange with silver, and a green glow, all great colours and there are LOTS more great colours.
Oh it goes without saying I hope you have a quality net and fish bonker, a nice cooler stocked with ice goes a long ways too.
Talk to the people who directly fish the spot(s) you are going to at the time of the year you are going. Makes the world of difference.
Don't forget your hooks and fishing line and beads (or you can buy pre-rigged hootchies) as well leave money in the budget to buy bait just before you hit the water.
