need help re correct sequencing of project

[boash21]

[attachment=12856]
New to gimp and working in to it bit by bit and getting dead ends partly I think doing things in the wrong order.
In the attached jpg I need to
1. select the round plate, rotate it slightly, and separate it from the background
2.fill the background with a solid colour
3. select a square around the plate slightly bigger so it sits against the coloured background.
4. set it up to print 8x8” at good resolution.
I suspect I am making a fairly simple task more difficult by doing steps in the wrong sequence.
Appreciate any help.  
eg get crawling ants around both the plate and background and can't do anything with it

I tell you why you think you get crawling ants around both - they are on different layers. If you select one (alpha to select - or select all) it will get crawling ants. Otherwise it should have just black & yellow dashes around it if the layer is selected. Otherwise if the lower layer has a selection in the middle inside the size of the top layer - the selection will show through that layer. You can get rid of any selections you dont want by clicking on select (from the top menu) and none.

If your plate is round use the ellipse select and copy it onto (as a new layer) the background of your color choosing, making sure it is 300 ppi when you make the background. Make a transparent layer above your background and below your plate. Make sure you have a horizontal and vertical guide at 50% each and centre your plate on the cross section. Using the rectangle select, in the tool options click on expand from center and starting at the intersection of the guides make sure your size in the tool options box is the same width as the height and you should have a proper square then.
Stroke this selection, fill it or both (However you want to go about it).

Maybe someone knows a quicker way to go about it.

Select the plate with the "Ellips Select Tool'  (marching ants) and press 'enter' on the keyboard
Invert the selection:  'Select / Invert' on the gimp menu
Fill the background with a color, use the 'Bucket Fill Tool'
Then 'Select / None' to remove the marching ants
Select the square you want with the 'Rectangele Select Tool' (marching ants)
Then 'Edit / Copy' and 'Edit / Paste As / New Layer
Set the original layer off
