If I were an undergeared and inexperienced holy pally I would be afraid to plea, pot, etc during that phase. First time we killed Nef (I'm a warrior tank, was in half blues at the time) I had an undergeared (but experienced) holy pally healing me (and only me) during p1. He was at 10% mana at the end of the phase, popping all his mana return CDs correctly. It was unavoidable, but manageable, we had him innervated for p2 so it was not an issue.
There are a couple options for your raidleader: 1)confront the pally about his CD usage (which should be done regardless), 2) switch the resto shaman to the nef tank, and the pally to the fury tank + the raid, or 3) get rid of your ridiculous fury tank strat.
Honestly, if healer mana is an issue, you are choosing the most stressful method for dealing with the adds in p1. If you don't have a mage (frost kite), or hunter (turtle tank, easiest method), then get one, you'll need these classes for heroics anyway.
I kind of find it a dick move that you would post on the forums about his mana in p1, when you are giving him the most difficult healing job (as you described it at least) for that phase. If his mana is an issue, move the healers around. If his replacement has an issue with mana, guess what it's your strat/comp, not the player. I'm not saying he isn't doing things wrong (he clearly is as others have posted already), it just seems to me you saw the overheal (which is not termendously abnormal when compared to a disc priest and a resto sham -> bubbles/earthshield/etc rarely overheal), and decided that he was the problem.
Personally I would address him about his CDs, but also address the raid strat/comp in terms of healing/tanking at the same time. If you do both, the guild will profit, and the guy wont feel so singled out.
