Simple RAW thread for 3.5 #31. By now, your question has probably been answered.

[Andezzar]

The questions were posted as Q 42-45 but the numbering is off

A 44

a) ask your DM. Can a character call a weapon that he can't even conceptualize?
b) Only if the DM decides that the object can be used as an improvised weapon.

A 45
Neither of those feats require a spellbook. If another class grants known spells that must be prepared the character can benefit from them.
a) Yes, but only if you fulfil the prerequisite.

Prerequisite

Wizard level 1st.

So you still need at least one wizard level, even if you want to master other spells you know.

b) Yes again, with the same restriction as above.

A 46

I'm not sure what 9th level alignement spell you are talking about but summon monster does not work. The Spell has the descriptor [see text] not [Fire]. Only when you use it, can the spell acquire the [Fire] descriptor.

Conjuration (Summoning) [see text]

[...]

When you use a summoning spell to summon an air, chaotic, earth, evil, fire, good, lawful, or water creature, it is a spell of that type.

A 47 partial

a) Most incorporeal creatures lack an STR score.

Sentient creatures without one of the mental abilities is impossible:

Intelligence
Any creature that can think, learn, or remember has at least 1 point of Intelligence. A creature with no Intelligence score is mindless, an automaton operating on simple instincts or programmed instructions. It has immunity to mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects) and automatically fails Intelligence checks.

Mindless creatures do not gain feats or skills, although they may have bonus feats or racial skill bonuses.

Wisdom
Any creature that can perceive its environment in any fashion has at least 1 point of Wisdom. Anything with no Wisdom score is an object, not a creature. Anything without a Wisdom score also has no Charisma score.

Charisma
Any creature capable of telling the difference between itself and things that are not itself has at least 1 point of Charisma. Anything with no Charisma score is an object, not a creature. Anything without a Charisma score also has no Wisdom score.
