Answer 1

Well for a start that is 43 cards with no land... so that means 17 land and that is way too low for some of the high mana spells you are stacking...

Answer 2

First, you need to get the card count down.  If you plan on playing a 60 card deck, that means you'll only have room for 17 lands with the current build.  I would cut at least 2 Radiants since they are legendary and the Angelic Pages since they aren't angels.  Twilight Shepherd is nice, but unless you play against a lot of board sweepers (Wrath of God, Damnation, etc), it doesn't seem necessary.  Seraph is too expensive for what it does so it can be cut too.  I recommend finding room for at least 2 Exalted Angels.  They're cheap for their morph cost and they have lifelink.  Even though you have ways to get your angels out faster, I recommend Etheral Haze or Holy Day to help deal with faster decks.  If you really want to get some good feedback for your deck, check out essentialmagic.com; it has a card search engine and you can get feedback on your decks too.
