A165) You should be taking magical training and precocious apprentice. Magical training gives you arcane caster level 1, precocious apprentice gives you a second level spell.
RAW, it can be a spell from any school or class list, since you don't have any schools barred to you and it doesn't specify a class.
RAI, probably any spell from sorc/wiz list, since magical training references the class.
Anyway, I'll keep an eye out...
The real hurdle is getting third level spells. For example, you could qualify for rainbow servant at first.
Wild soul's biggest issue is the second level spells and eight ranks of know(arcana)...
Bonded summoner needs 2nd level arcane spells, a familiar, and eight ranks of know(planes)
The Havoc mage needs bab +4, as well as 2nd level spells.
Can't find any others...
Your best bet is to dip cleric and go into mystic theurge, honestly
Q166) What base classes gestalt well with survivor? It seems like you should be able to compensate for the low hp, bab, and skills with something.
