Does ext3 allocate indirect blocks as needed or is there some fixed number of these like inodes?  Should I be concerned with running out of indirect blocks?

ext3 allocates them as needed.

In fact you will often see them allocated consecutively with the data blocks they refer to:

debugfs:  stat bigfile
Inode: 12   Type: regular    Mode:  0644   Flags: 0x0
Generation: 330185944    Version: 0x00000000
User:     0   Group:     0   Size: 8388608
File ACL: 0    Directory ACL: 0
Links: 1   Blockcount: 16450
Fragment:  Address: 0    Number: 0    Size: 0
ctime: 0x4db5f1c8 -- Mon Apr 25 17:12:24 2011
atime: 0x4db5f1c8 -- Mon Apr 25 17:12:24 2011
mtime: 0x4db5f1c8 -- Mon Apr 25 17:12:24 2011
BLOCKS:
(0-11):2561-2572, (IND):2573, (12-267):2574-2829, (DIND):2830, (IND):2831, (268-
523):2832-3087, (IND):3088, (524-779):3089-3344, (IND):3345, (780-1035):3346-360
1, (IND):3602, (1036-1291):3603-3858, (IND):3859, (1292-1547):3860-4115, (IND):4
116, (1548-1803):4117-4372, (IND):4373, (1804-2059):4374-4629, (IND):4630,  ...

... and so on (IND/DIND are indirect & double indirect blocks).
