Godson, most stuff there is solid for a barebones impression if you're trying to get it all at once in a hurry for cheap. Quite a bit of the items you're picking up are "10 foot rule" good but you're paying cheap for stuff that will possibly have buttons pop off or stitching getting torn. So you may want to be handy with needle and thread or pay the extra dosh for your items.
Your uniform and field cap... STAY AWAY FROM HBT! Save yourself the trouble and go ahead and grab wool. You'll curse the wool when you're sweating through it in summer, but praising it when you're cold as balls in the winter - when most events are! Get HBTs second and only good repros. Not the monstrosities in your wishlist. I recommend getting your cap and wool uniform from Hessen if you can afford it. It's still chinese shit, but it's the best chinese shit. HBTs were not immensely as common as the wool uniforms and you'll look sharper anyways!
Also, on the topic of your boots... those Swedish boots are just as bad as wearing a pair of black mountain boots. I recommend shelling the money on a proper pair of boots that will cost you a lot! Stay away from rubber soles. You want hobnails. SM Wholesale has some in stock right now for over $200, but At the Front (
www.atthefront.com) should be getting $150 low boots sometime in stock before Christmas, so buy there! I certainly will.
With wearing Y-straps you don't really need tunic hooks. Those are only absolutely necessary for early war when they didn't have Y-straps for the regular infantry.
I see you placed the nice quality German socks on your Hessen wishlist. If you're trying to be economical (I'm more than certain you're trying to be) I suggest you buy their foot wraps instead of the socks. Go ahead and get 2-3 pair of foot wraps so you'll always have something to change into in case you get rained out or you don't want your feet freezing at night.
Speaking of getting rained out, you will want to get a waterproofed zeltbahn (shelter-quarter) to be able to wear as a poncho and use as a lean-to in case it rains. I've seen some farby reenactors at some events I've been to where they are wearing just HBTs with no zeltbahns as ponchos and almost get hypothermia. They ended up leaving the event early because they had nothing to change into and were feeling sick.
If you're able to, try talking with your Ausreenact group about buying items from them which you may get for MUCH cheaper!
