Does ext2 have a fixed block size to avoid fragmentation?  

One approach I've heard of is to avoid having minimum size blocks
allocated on the premise that a free block needs to be of a certain 
size on average to be used by a new file.  In dos world you use
minimum size blocks and pack them tightly.  In Linux world I
understand that data is written across an ext2 partition fairly
even, how is this accomplished?  Dos world is not bad if your
not deleting files in the middle of your data whereas Linux
world ext2 seems to be reasonable in the average situation.  

Is an inode in a table containing absolute low level physical
address, link count, permissions, and name?
