A building would have an AC, although it would be fairly low. (A city wall was described as having AC 3 in the online d20 SRD.) More importantly, the walls of the building can be described as having a certain number of hit points and a level of hardness dependent on the materials used to construct it. When figuring the damage from an attack, reduce it by the material's hardness and apply the rest to the hit points of the structure's wall. When the wall's hit points are reduced to zero, it's destroyed.
The rules for Smashing An Object and Walls will be useful here.
Spells On Levelup
You get those spells in a spellbook, by RAW:
At each new wizard level, she gains two new spells of any spell level
or levels that she can cast (based on her new wizard level) for her
spellbook
But, you don't have to put them all in the same book. In fact, a standard spellbook only has 100 pages, and each spell takes a page per spell level. So you'll likely run out of pages and have multiple books, or make the investment in a Blessed Book.
"For her spellbook" implies to me you only get it for free in one book, though it doesn't say so outright (it also doesn't say you get them in 17 books). If you want to make dupliate copies of a spell, there's rules for that:
A wizard can use the procedure for learning a spell to reconstruct a
lost spellbook. If she already has a particular spell prepared, she
can write it directly into a new book at a cost of 100 gp per page (as
noted in Writing a New Spell into a Spellbook, above). The process
wipes the prepared spell from her mind, just as casting it would. If
she does not have the spell prepared, she can prepare it from a
borrowed spellbook and then write it into a new book.
Duplicating an existing spellbook uses the same procedure as replacing
it, but the task is much easier. The time requirement and cost per
page are halved.
Does a spellbook have to be a book?
A spellbook is an actual item in the item list, and is mentioned numerous times specifically. You could interpret that to mean it has to be a book.
That said, Complete Arcane has rules for differing types of books. A book made of something else is still a book, and the cost of copying the spells is the same unless CArc says otherwise. For something like bone fragments, it doesn't: the extra cost is in buying a book made of that material.
So yes, in that case your free spells could go into anything that counts as a spellbook in that way. On something else, it becomes undefined and is up to your DM.

No, there are almost no official alternative reincarnate charts
It's likely the expectation is that the DM adjusts the chart based on his campaign. That's because, if I remember correctly, when Dungeons and Dragons, 3rd Edition was in the planning stages, one of the complaints fans of Advanced Dungeons and Dragons, 2nd Edition had was the necessity of cross-referencing a brand new 2nd Edition book with many other, sometimes out-of-print 2nd Edition books. To mollify detractors, the 3rd Edition design paradigm was to keep books as self-contained as possible, using references to other sources only when absolutely necessary. This continued into the 3.5 era, and explains, for example, why there're no comprehensive D&D 3.5 random encounter tables and, for example, why monsters who would benefit greatly from the feats Martial Study (ToB 31-2), Travel Devotion (CC 62-3), or Shock Trooper (CW 112) don't have those feats and, instead, have feats like Alertness (PH 89).
