Congrats on your first All grain brew day!
Looks as though you hit your OG pretty good even though it was over a 1/2 gallon. That's a good thing! As far as using US-05.... I wouldn't worry about it. Seems as though it's gonna turn out to be a nice American Ale. Very drinkable I'd guess. But... you never know how it's gonna ferment out. Depending on your setup that is. Especially your fermenter temps. I'd ferment around around 64-68 F. That's my opinion though!
As far as being easier than it sounds... wait till you have a hankering for wheat beer, rye beer and or a recipe that has multiple adjuncts. Only because you'll hafta find a way to "tweak" your system to that specific recipe.
