I prefer unscented 69p a packet baby wipes to paper towels, nothing like sprucing up a finger printed setup than a baby wipe and I buy them by the case for doing mechanics or fixing computers, damned useful 
A good large syringe and needle will be almost an essential to the filler needle, a few pennies and you can get blunt ended ones which makes salvaging juice out of attys a lot easier.
Q tips for cleaning out the connector? They do sometimes get a bit juicy or they get a black rime on the contacts. Last suggestion I would with an ego setup is a lanyard, oh how much life got easier with a cheapo lanyard, stops the unit rolling about, hang it round your neck when on the move, less likely to lose it or drop it either
Good luck with it all
