Yes, you should consider upgrading the firmware. That combination of
PRI/STA firmware is known to have a bug that causes corruption of data
on PCI bus. This was fixed in PRI 1.0.7 / STA 1.3.5, so it or anything
newer is probably better solution.
I would recommend first testing with volatile upgrade to make sure that
the new firmware version actually works with your card and there are no
unpleasant surprises waiting to happen. At least some people have
reported dropped signal strength/quality with new firmware versions. It
is possible that the PDA on the card does not include all new
configuration values and the defaults in the firmware image are not
optimal for that card, etc.
If you are going to download firmware images with Host AP driver, please
use the latest CVS snapshot of it.

What do you mean with "Prism 2.5 kernel driver"? orinoco_pci?
hostap_pci? If you plan to use two different drivers for the same PCI
card, I would not link them into the kernel image.. If it is only one
driver, then it should be OK to link it in.
