Definitely upgrade to 1.2.9-1. No point sticking with 1.2.8. 1.2.9 has 
been out
since june. This is a no-brainer.

To 1.4 or not, with less than 2 weeks before golive, is a harder call. 
If nothing
else, it would also require a kernel upgrade.

We fix bugs in both releases. Actually, all three when you include the 
mainline
kernel. The one open issue with 1.4 is an EIO when doing odirect ios on an
unaligned sized file. This is not in 1.2. It has been fixed in mainline. 
1.4.2
will have the fix.

The good news is that you can always upgrade to 1.4 later. As in, the ondisk
format is the same. So unless there is a feature that 1.4 provides that 
you have
to use, I would suggest you stick to 1.2 and plan to upgrade to 1.4 in 
the near-term.
