You forgot at or going to the Forinthry(?) Dungeon for slaying greaters =P
I think what makes people a target usually is just the ability to attack you. Pkers are usually just bored and if you're in the level range for them to attack you, then you're most likely going to be when they're not really risking anything anyway. (Claw rushers etc)
If your plan is to head into the wildy for occasions when armour isn't required, it's worth doing so e.g. Penguin hunting. Usually I won't find a case of anyone going out of their way to attack penguin hunters on world 60 because everyone knows not to bring in their expensive items. Another reason to not bring more then 3 items for wildy pengs is for when I head to the lava maze and intend on getting killed by the kbd or normal black dragons at the centre, a quick way back to the normal area of Runescape.
It might be worth putting on some ganodermic's or dragonhides if you're heading to charge orbs at the obelisk, just 3 items and make sure not to get skulled. Just for that added protection against pkers trying to bind you, but really isn't necessary.
Using the abyss, again I might bring black dragonhide armour just to increase my defence against being binded and maybe a glory teleport, but if you're not quick enough then a 1 click tab could be of use. Bank the runes you make as to not lose 10k or however many you make if you happen to die and you shouldn't be too worried. You can buy back the large and big or whatever at the rcing guild if required.
Chaos tunnels are so close to the wilderness edge as well that you can quickly teleport away in the sign of danger or get there before you're attacked and because it's not a consistent thing (You're only usually heading in there to either do you're daily Bork once a day or the occasional Slayer task which once there you can't be attacked anyway). You should be fine to bring whatever is needed, any signs of trouble, feel free to place private to "friends" or "off" and hop to another world if you're really that scared.
Finally the Forinthry dungeon or however you spell that. Usually I have to downgrade my gear abit to head there since the greater demons are at lvl 22 or 23 wilderness so it's just out of reach to teleport (lvl 20 wildy). I'm abit risky and keep my slayer helmet on, but if you're not willing to risk it then neitz is another option. I wouldn't bring any Bandos armour. A good option is proselyte, not too expensive to get back and you can just pray for the entire task and smash them down. Another thing to note is I'll only bring 1500 cannonballs, don't want to bring all of them in one go as then you'll be hurting as well. Finally make sure not to bring any berserker rings or onyx amulet, you could just bring a ring of life for safety purposes and a amulet of glory for quick teleporting again by running 2 wildy south in the case that danger does come and you need to teleport.
I personally haven't run into the occasion that a clan has come, all you can do is hope they're too disorganised that they don't stop you from teleblock you and you're fortunate enough to not be binded, when in reach of wave 20 teleport away, else just keep running
Cannons aren't a loss at all, you can just head west of the prayer guild/edgeville and reattain a cannon from one of the dwarves in the building, you'll have to go to Falidor if you have a gold or royale cannon though to get it decorated again >.<
