1.) Well, with the right perks, Conjuration/Illusion can be all you need, so it's safe to dump all your points into Magicka instead of Health and Stamina. That being said, you'd also get murdered from one stray arrow or spell.

2) Since all the - Thrall spells are two handed, you can't dual cast them to make them stronger or anything. I think the only master spells that have some increased duration like that is Dragonhide and Mass Paralysis, though technically they SHOULDN'T be able to be dual-cast.

As for casting them again.... If you have the Twin Souls perk for conjuration, you can have any combination of 2: atronachs, like flame or frost, or undead that you raised. If you do not have Twin Souls, then you can only have one. For example, you conjured a Flame Atronach. Conjuring a Frost Atronach will cause your Flame one to disappear. But if you have Twin Souls, both stay. Now, if you have both a Flame and Frost summoned with Twin Souls, and cast say... Conjure Storm Atronach, then the Flame will disappear cause it's the first one you summoned. If used with undead, any person reanimated with Dead Thrall will NOT turn into ashes. Any other reanimate spell will turn them to ash though.
