Multiple stronghold and planar sphere mod Options

[Roy]

I'm reinstalling BG2 now and wanted to ask if I'll see all the new stronghold
quests with the multiple strongholds component from ease of use.

Is the new mage stronghold quest compatible with the planar sphere mod?

One tactic in battles I have been using lately when on one tough boss
who uses melee or some other tough monster is running the character
he is attacking.

Usually he runs a little after him before choosing another target,
than I do it again and it helps.
