Here, let me see if I can help you a little bit:
Disclaimer: Intel is already a bit old, but these locations are more determined by topography than groups living there, so are probably still camped.
So, here are the major camp issues you're going to run into living around Aridia:
Vehan/Udianoor: The big one. Typically camped by smartbombers and/or instalocking setups with medium-heavy support. Not clearable by a small group; advise making the trip during the off-hours of whoever lives there (if they have one) or bypassing entirely.
Hier - probably the next most heavily camped system. Sometimes has instalockers, but not as commonly as Vehan/Udianoor. Advise using covops ships.
Shirshocin: When I was living there this was rarely ever camped, but it used to be a big camp spot and I've heard lately that people have taken to sitting on there again with tackle and artillery boats at range. Suggest fast-travel stabbed setups or covops.
Nalnifran/Shafrak: Here's a weird one. Sometimes alliances will set up on that side of Aridia for nullsec antics; when they do, those two systems often get camped up (either by people looking to catch people trying to join their nullbros, or by the nullsec groups themselves doing security ops). Quantity and the duration of camps varies significantly.
Hope this helps somewhat, at least.
