when i go to my mesh in windows>outliner my image for the mesh is just a white rectangle no red arrow and when i shift p it i get a warning in the bottom right hand corner saying warning veste is already
the parent of the child

You sure the warning doesn't read "veste is already a child of the parent world" or something similar? because that's the only warning that would make sense, it tells you that there's nothing you can unparent the object from. Which would be the case if it wasn't in a group. Which is how it should be, so everything is perfectly fine. (I told you, you only need to hit shift+p if it is parented under the symbol I described... )

i actually think that i messed up when i had to go to keyframe 1 for i had a number ranging from 1 to 24 under my model viewer and next to thatis 1 to 48 however that is a text entry not a button so were do i go to
correctly do this

The inner numbers (1-24) tell you the lenghth of the timeline you're working with. The outer numbers (1-48) tell you the whole length of the animation. They are text entries because you can type numbers in there to change the length of the animation. To go to keyframe 1 click on the timeline itself, not the text entry thingies. Then you can hit S to set a keyframe for the object you have selected. This should cause a red marking to appear on the timeline.
