Studio Layout advice needed badly.

Studio Layout advice needed pretty badly for a recording noob. I have several questions about how I plan to setup my room, and need some advice.
The shape of the room is simliar to the one in this diagram I found from another thread. Mine however is 10.125' wide and 11.75' long.

1) The only piece of furniture in this home studio other than the desk and chair will be one of those papasan chairs. It will be down in the bottom right corner if referencing the picture above. Will one of these chairs be good for absorbing bottom end frequencies for that corner, or should I still go ahead and use some traps behind the chair in that corner???

2) Again, if referencing the picture of the studio layout at the top of this post, between where my two speakers will be, there is a 42" wide window. I am trying to figure out what to do over that window. I'm pretty sure the best thing for speaker placement is to put them just to the sides of the window, but no further than that to avoid putting thme right in the corners of the room. then directly behind the speakers, I'm putting a few square feet of 2" foam. Other than that, should I plug the window and cover it in 1" or 2" absorbers, or should I build a quadratic diffuser to cover the window and fill the space between the speakers???

3) My last question for now is what to do with the wall on the opposite side of the room as my speakers. Obviously I will be bass trapping the corners, but in the middle of that back wall will I be better off putting up foam absorbers or a diffuser or both??? Sorry too be such a noob, but I would rather try to do this decently the first try as opposed to spending a bunch of time and money only to end up with junked room. Thanks guys.

Trap all 4 corners floor to ceiling if you can. Your speakers should be out into the room so you're listening in the nearfield when sitting at 38% so they'll be several feet from the front wall. Even just some nice heavy full curatins will help over the window.

On the back wall, I'd put the papasan centered on the rear wall and potentially a 4" panel centered behind your head.

So you think the papasan being in the center will help keep the symmetrical layout of the room more in check???

Wouldn't he be better trapping the 4 corners with just 4x2 panels, and using the other 4x2s in the wall ceiling, or even 2x2s in the wall wall ceiling corners?

Well, my thought was that since the length and width are so close together, I'd like to get as much as possible at the ends of those dimensions. The 4 vertical corners floor to ceiling accomplishes that.

Now, you could certainly do a single 2x4 in each vertical corner and then trap the front and rear wall/ceiling corners up high by straddling them. That will give you more in the height dimension and still hit the length pretty hard.

Either way, it's the same square footage of corner treated.
