I'm in a campaign full of relatively new players (myself included) and I had a few questions for you guys.

One of my friends who knows a whole lot about DnD says that there are few (if not no) divine caster Prestige Classes that don't give you full caster progression that are worth taking. So what are good PRCs for a cleric (focused on fighting more than healing, and he has low charisma) and a Water-focused Shugenja? (we're only level 3 right now, trying to plan ahead).

Also, what are good feats or spells that a low-charisma cleric can take to boost his combat abilities? Divine Might and the other divine feats from the PHB2 all rely on the charisma stat.

Also, I was looking at some Reserve feats in Complete Mage and the Aquatic Breath feat says it gives +1 CL to water-based spells. As a shugenja, I get most of my spells from being elementally tied to water, so would the spells I get from that be counted as "water-based spells" for the purposes of that feat?
