That's a great first script! Best thing to do is to break down your idea into blocks. Selecting your secure and the salvage bag is simple: (do for each container)
display ok Please select your container
set #TARGCURS 1
repeat
until #TARGCURS = 0
set %container #LTARGETID
You'll want to open both of these containers, so you should do (2x)
set #LOBJECTID %container
event macro 17 ; use last object
wait 20
After that, you need to find the #FINDTYPE for the tool, and the #FINDTYPE for the circlets. You "use" the tool like you did in the above snippet to open the crafting gump. After that, you need to click some places. I think for now I'll let you play a bit, but that'll get you started.
Things you'll need to read up on are:
finditem
exevent DRAG/DROP
click
#CONTNAME/#CONTSIZE for waiting for gumps you want.
