Actually, Ive been doing AoE since lvl 52 (lvl 65 now), no oop supports, no tank, just me, my merrow and newbie buffs. The trick to doing it is not stand around. Kite as your life depended on it (because it actually does, if the pony dies, the agro WILL be transferred to you and you will most likely die).
My first AoE spot was skyshadow Meadow (connabi groups, the others have healers and stunners), just right under Oren, the mobs are 1/2 HP passive groups, so you can kill them in 2 nukes. To aggro 1 group, order the pony to nuke one of its members in a was that preferably the aoe affects all of them, then move a bit away so the pony follows you and count 5 secs (the pony skill cooldown) and order the pony to nuke once again, that way, the probability of the nuke being interrupted is less and the damage taken by the pony is easily healed in 1-2 casts, and such you can save you mana a bit. Of course, you still have to do mana breaks, or just summon boxer and recharge you mana, so you dont have to stop that long.
And just a warning: Don't try to kill a group when you have under ~250 mana left, if the pony gets interrupted to much, and you dont have enough mana to heal it, youre screwed, also, try to do larger pulls every time your servitor UD coolsdown, it gives you a nice exp boost every 10 minutes or so.
Just to finish, I will leave here some nice Aoe spots that you can try:
Tanor Canyon (I tried it but it was too risky because at that point the pony is not good enough)
Skyshadow Meadow
Frozen Labirynth (Lost Bandersnatch and after that Ursus)
Ancient Battleground (big groups, have stunners, are aggro and they HURT, only for 62+, all undead, so if you ca get access to holy weapon on the pony, it helps)
Silent Valley (high lvl only)
****...that was longer than I thought! If you still have doubts, go to
http://l2pets.com/forums/index.php thats the best summoner community I know and if they helped me I think they will help you too.
Good luck AoE'ing!;)
All of the places you've listed are 1/2hp mobs area. Without oop buffs and exp wise, it's better to just solo in some herb dropping area. (I did exp in skyshadow meadow before for the stupid Spellbook drop b4 npc sells them >.<). You loss time in exp since you needed to run around to keep the pony alive. But if you're just exping in the 1/2hp so just you can aoe and not care about exp/hour wise, then it's fine.
It's going to help in pony aoe if you can get access to Acumen3 and/or PoWater though, then I find worth it to aoe in 1/2hp mobs area :p
