I actually created a spells available according to diety in my campaign. Each cleric has the same number of spells "known" but from different list. Once you worship someone you get their spell list but no one elses. Knowledge Religion lets you know what spells X diety provides. I chose all my spells from PHB and Spell Compendium to make it easy. Some clerics have wizard spells and etc. It worked out pretty well.
Almost all clerics know curatives but there is a campaign reason why that I designed into the game as well as why they turn undead.
