Just a few things that I use when modeling that I don't see listed and is a must have, a plastic spruce cutter, paint thinner, I go with MM paints when I started building in Sept I ran out and bought the little testors bottles at Michael's, big mistake!, that may work for light detail painting but you might want to go with some of the model master or tamiya paint.
Oh and tooth picks buy a box of them I constantly use them. An asortment of paint brushes some of the detail is amazing and you will be frustrated if you don't have the right brush for the job. A different varitey of sand paper, rubbing alcohol, airbrush and compressor, don't make the mistake that I did and buy a cheap air brush cause like me you will have realized you should have just gotten a good one to begin with.. My last air-brush was an iwata and was like $140.00 you have to be anal when it comes to cleaning them but it will work great..
Oh man just thought of some more must haves tweezers, super glue, wire, triangle, metal ruler and electrical tape. If working with fiber optics you will need another type of glue is use elmers all purpose white glue for that.. I think thats about it I am few months in and it always seems like I needed something but I am just reaching that point where I can work and have me basic needs.
Hope this helps!!
