The amount of files and directories on an ext3 file system is limited by the available inodes. The remaining free inode count is listed by tune2fs -l /dev/sdXX. Dunno about ext4, but I suspect it's the same, maybe with an other command than tune2fs. You can change the inode count when you make the filesystem.

No, it is quite different on an extent based filesystem like ext4 (or XFS). The limits in ext4 are effectively theoretical. You won't hit them. You could create a new file every second for 127 years.
You can change the inode count when you make the filesystem.
