Some more tools you'll nead also:

Access to the same room as your target. So a good breaking and entering kit.
And maybe some good disquises for when your stood next to the target.

After all bluetooth only works upto, what 10m. I have read that developers are looking into the possibilty of getting it to work at distances off 1 hundred metres. So bluejacking maybe something to worry about in the future but imho, untill the technology reaches the stage where bluetooth radio waves can pass through walls and go beyond a reassonable distance this should not be of concern.

I use bluetooth a bit i sync my phone and outlook on my laptop, also i use it to access the net with my hand held via my phone when i'm out and about. So i no how limited the current technoloy is, the signal will not pass through anything more dense than a paperbag.
