Feats = 1st Practiced Spellcaster (Clerical Spells)
3rd Practiced Spellcaster (Wizard Spells) and Scribe scroll (Wizard Bonus)
(Rest of Feats would concentrate on Item Creation)
Since I will only have three HD in other levels I will only get a 3 caster level boost but that should help, at least on certain spells, make up for lack of level progession initially.
The Practised Spellcaster feat gives a boost of +4 (to a max of HD) - that is you don't get to boost your caster level in a given class to more than your total hit dice - for you PC Cleric 2.wizard 1 you would have a CL of 3 for both cleric and wizard spells.
Note that this doesn't grant you access to spells only effects that depend on CL.
