Daniel, excitement can lead to disaster when it comes to imaging, just keep it simple, and take it easy.
Start off with a few lights, say six, then take your darks during or after your lights, at about the same temp.
ISO nothing over 400, on occasions when it is needed maybe 500-600, and don't overdo your exposures at first until your get experienced with shorter exposures, and from there move on as the experience grows.
