Your choice is o.k. RELENG_4_5 will only have security updates on top
of the 4.5 RELEASE .
RELENG_4 will get new features in addition not available until the 4.5
RELEASE.

Nope. Some new features are introduced from time to time. Track the
"stable" mailing list!

PIO has nothing to do with IRQ (interrupt requests). Newer drives are
able to use DMA instead of PIO.
This will decrease processor load and increase drive performance. Your
CDROM seems to only support PIO mode.
