blender newbe issue

[loy67]

hi,

i just download blender 2 week ago and start play a bit. my goal is to do some clothe, so i need first animated caracter so i start animated sequence with mixamo.

when import fbx file, blender put all in the upper right windows, but there is a lot of thing here i'm not sure what could i do or not. ( so add little screenshot for detail)

 

about the "1" :

when check detail of thiese element there is nothing in, could i delete it ?

 

about the "2":

it's one section for animation, but in my mind, i only use animation, pose and armature could i delete the skin related thing ? ( i already have this same file in the "tpose" section at the botom)

 

 

thx in advance ( very newbee, sry about that's ^^)
