This is a bearing wall 13' wide with a 48'' opening in the middle 1-2x10 header
Im wondering if this are problems and how to fix them before hanging the drywall




King stud other side not nailed to top plate.
Should I nail it same as the other side?


Trimmer not nail to header
Is this OK?

Not visible but header is not bearing on trimmer other side[1/8 gap]
Should I shimmy it?




Othar studs/ top plate no visible nails
Is this OK?


Top plate bears only on half of stud
Should I sister with a full lenght stud to existing and also nail it to the top plate ?
Can I substitute nails with screws?
Thanks a lot

 

Minimum bearing for a stud,joist or rafter is 1 1/2". No need to sister and aside from some dust the framing looks beautiful.
