Evox23,
I have a similar kit but I add a small sippy-tip water bottle that I pre-fill with tap water for irrigation and rinsing purposes.
I don't bother with sterile gauze any longer...Just folded up kleenex or paper towels or even the paper hand drying towels in the public bathrooms...(out of luck if they have hot air dryers!)
I don't bother with tape or sticky stuff during the day...I use a 1/2 xtra large mini pad stuck to my underwear and the kleenex...that covers things nicely...I just change the kleenex when needed...the mini pad protects my clothing...things do not move around too much so I am safe (I, on the other hand, move around a lot so it kind of works very well and saves me a lot of money).
Why the spray? Do you work in a small office? I have not worried about odor in 30+ yrs...honestly...what do normal people do? They stink too 
I also find that pencil cases or make-up cases are my favorite kit bags...Dollar stores are my friend...I pick up about 10 at a time when in the States...I measure them first to make sure that my syringe fits in...I get pretty colors, sometimes the ones with 2 or 3 zippers so that the lube packets stay dry and separate...
