New Build in Northern MN

So this is my first thread and first semi-dedicated theater build. I'm hoping that posting in the forums will keep me going and provide great feedback. I have been reading for a while and doing lots of thinking, but now it's time to get started.

Progress will be slow as I have a full-time+ job and family and other concurrent projects (like landscaping and more) and this theater build will include finishing the whole basement.

I'll try to get some before pictures up soon and try to put what's in my head on paper or visio or something to give an idea of the finished product.

I have put some thought into sound isolation, and lighting. Right off the bat I should ask, is there anything that you forgot or would change before you started your build? Experience can be a great teacher and I hope to learn from anybody who reads this.

Thanks!

Ok, so making a drawing is more time-consuming than I thought... I always thought I wanted to be an architect, but now I see why I never did. I made a drawing of my basement to near scale on the iPad. I hope it helps give a better idea of what I'm working with.
As I look closer, I am wondering if my post is in the right section. I want a dedicated theater, but it will share space with the family room. I plan to separate it from the rest of the space with lighting and decor, but it will not be a total sealed, soundproof, isolated room like so many others.
When you are in the theater, I still want you to forget about the rest of the house, so the decor and sound isolation are important to me. I have read a lot so far in soundproofing, but still consider myself a novice. My plan here is to do insulation in the ceiling and double drywall with green glue and a double wall for the shared walls between the bedroom and hallway. Soffits, paint and lighting will also help separate the space.
Money is an issue (isn't it always?) so I will do most of the work myself and thus, will take quite a while; and my setup will not be overly fancy. I still want it to be nice and professional, so I plan to find help when I'm above my head.
Next I will post pictures of the current space. Thanks again for your help and suggestions so far.

To help with the image, the plan is roughly 30'x60' and the screen will be on the wall shared with the bedroom. I plan to have a small stage below the screen and two rows of seating with the second row elevated. Soffits are in light dashed lines. Once again, scale is not perfect, but you get the general idea.

Someday,yes, but I plan on making a double wall (isolated from each other) to help with sound issues and insulation as well.

Been busy with landscaping lately, so no time for the build. Digging planting areas and planted 40 trees and 70 shrubs. I'm feeling it!

I have been thinking lately and wonder about going with full 7.1 or just doing 5.1. My final room size will be about 16x12. It seems border line to me, and saving money on a few speakers and wire is always good, but I dunno. Figured I'd get some feedback from you all.

Thanks!

Thanks, BllDo. I am planning on putting several jacks in the AV closet (putting it all under the stairs). Do you think I need jacks in the room? I was contemplating adding the ability to do Xbox or PS3 or WiiU in the theater, but also wasn't sure of the best way to do that.
