Didn't you say that the POD was on the way, and that you didn't have it yet?
In that case, I agree with the keyboard amp recommendation. The reason is simple: if you want to use the POD amp and cabinet models, then you DO NOT want to play through a guitar amp. A PA is the best choice, and a keyboard amp is essentially a small PA. Most K/B amps give a fairly "pure" amplification of your sound.
I play through a POD xt Live, into a direct box to the church PA (pro quality), and use the direct output of the direct box to run a line into a Hartke B30 bass combo that I use as a monitor. At home, I play it through a Peavey K/B 3 combo.
Using a guitar amp for a POD basically sends your guitar signal through TWO preamps, double-coloring your tone, usually with undesirable results.
