I agree with alspal that Construct 2 General is not the best place for this thread.
Hopefully we can get a KS and/or tutorial forum!
As you point out, there are dozens of technical details with regard to running a KS campaign (you could just as easily have described all the steps to setting up an independent website to use for reward management, integrated shopping, web-public project updates, long-term sustainment of your backers as an opt-in mailing list, a place to handle Paypal during and after the campaign, etc.!), and while I think most people know how to open a bank account, you have both the knowledge and the inclination to share your expertise with others, and I hope now that you're in between semesters, you take the time to do so!
=P I wouldn't say that you "missed" anything, since you were primarily just establishing your bona fides by listing some of the steps/considerations a KS project manager will have to deal with as a brief example, and discussing the scope of your KS experience (very cool!), but when you mentioned that Kickstarter will provide a 1099-K, you've touched on a much larger and murkier issue: local tax regulations!
Amazon Payments, for example, will definitely send a 1099-K not just to you but also to the IRS, reporting your income, so the burden after that falls on the project creator to handle all local tax laws. As has been discussed on Forbes/ Kickstarter's Sting in the Tail: Tax, The Daily Dot/ The Hidden Cost of Kickstarter Success, and even individual tax firms' websites, you have to account for Federal and State taxes, the applicability of sales tax and the implication of shipping to states in which items were manufactured, you could well wind up owing self-employment taxes, and in the U.K., HMRC is going to view your rewards as pre-sales subject to VAT.
It's a mess, and the best advice is to hire a CPA or other tax expert to advise you on the particulars of your campaign. In many cases, consultation will be free and you will only be charged if you take advantage of their actual tax preparation services.
