Size of journal and resize

[Duško Rusmir <drusmir gmx ch>]

Hello

I have some large Partiton at 2 GB, 4 GB, 7 GB, 13 GB,  25 GB.  How 
big I need the journal for its?

Could I resize ext3fs with resize2fs,  ext2resize-1.17 (with 
ext2prepare, ext2online), parted-1.4.21 Tools?

The Partititons Magic 5.0 I can't use with ext3 only with ext2.
