How about bringing in some structure to the whole thing? May I be so bold as to suggest the following:
Class X - Major benefit, minor benefit - Particularly profitable to class X (reason, if not obvious) - also profitable to ..
Example:
Paladin 2 - CHA to saves - Sorcerer - any CHA-based class
Of course, one could design different entries for the same dip, given that different classes may profitate differently from the same dip. A good example is Monk 1/Cleric X and Monk 1/Swordsage X:the Cleric wants Wis to AC, the Swordsage wants free IUS and Stunning Fist. Which would give, from the start with a few additions from me:
Barbarian, Lion totem 1 - Rage, Pounce - melee classes
Binder 1 - Naberius vestige (heal 1 pt. ability damage/round) - Hellfire Warlocks
Cleric 1 (General) - Turn/Rebuke Undeab - spellcasters (Divine Metamagic) - access to Divine feats
Cleric 1 (Charm domain) - 1/day +4 CHA - Paladin, Sorcerer, Hexblade - any CHA-relying class
Cleric, Cloistered 1 - all Knowledges as class skills - Archivist (Knowledge devotion) - various access to prestige classes (War Mind comes to mind)
Dragon Shaman 1 - Presence aura, Senses aura, Vigor aura - support characters
Dread Necromancer 1 - Rebuke Undead - Cleric
Duskblade 3 - Arcane Attunement (Detect Magic SLA), Arcane Channeling - access to Arcane Strike, Spring Attackers
Fighter 2 - Bonus Fighter feats - martial builds
Hexblade 2 - Arcane Resistance (CHA to saves vs. magic) - CHA-based classes
Hexblade 3 - as above, plus Mettle - Paladin of Tyranny, Paladin of Slaughter
Knight 3 - Bulwark of Defense (threatened area counts as difficult terrain) - melee control builds
Marshal 1 - Skill Focus (Diplomacy), Motivate Charisma - Diplomacy-based characters
Monk 1 - Saves boost, WIS to AC - Cleric, Druid, Psychic Warrior
Ninja 1 - Trapfinding, WIS to AC - as Monk 1. Note that Ki Power virtually grants you +2 on Will saves

Psychic Warrior 2 - Bonus feats, WIS-based manifesting - martial builds
Ranger 1 - Track, minor saves and skill boosts - Druid, Scout
Ranger 2 - As above, plus Combat Style - various combat builds
