There is also this to consider: Posted about the same time as the original poster... Sorry Folks, iPhone 7 Home Buttons Aren’t User Replaceable WRITTEN BY JULIA BLUFF Bad news for the DIY-inclined: looks like the home button in an iPhone 7 or 7 Plus can’t be replaced with a different one. If you break the button or rip the cable, you’ll have to go to the folks at the Genius Bar for a repair—or be stuck with a completely non-functioning home button. .... The iPhone 7 and 7 Plus appears to take this feature a step further. Home button replacement—or damage to the original home button cable—renders the button completely non-functional: no Touch ID and (here’s the new part) no return-to-menu ability. You can still navigate your phone by turning on Assistive Touch. But for all practical purposes, you’ve got a dead home button. One that you can’t fix on your own or at an independent repair shop. ~~ Read the rest here: https://ifixit.org/blog/9020/no-fix-iphone-7-home-button/
Thanks for the help, but after I posted that I did a little more digging. Turns out that the video card tries to power up when the machine gets plugged in, and every time I plugged it in, I let a little more of the magic smoke out. I used my eyes to trace where the smoke was coming from, and sure enough I found some blown ICs on the graphics card. Put another card in and viola! IT WORKS!!!! Something in the short circuit on the GPU card must have been dragging the power supply down or something… Thanks for the help, but it was not the power supply! What an odd one!
IF when you are putting your new screen in, and it looks different than this picture, make sure you routed the cable properly, with respect to the antenna you just reinstalled. Its very easy to route the display cable around the antenna the wrong way and have a bit of extra cable flapping around when you are done. It should look nice and tight like this pic shows.
Also, enricolimcaco is right. These screws are T3, not T5

Mine are T4. Make sure your bit fits snugly!
I have T4 sized here. Same with a lot of the other ones. Make sure your driver fits snugly!
A lot of these are actually T4, not T3, so be sure to use the right bit. It should fit snugly.
Love how the battery changed to an iFixit branded battery, in the phone!!!!
