Spell Selection for an Gish (Sorc)//Assassin

[Dusk Eclipse]

For a solo game I am building a level 10 gestalt Rakasha//Cloistered Cleric 1/Rogue 4/Assassin 5

Rakasha's can cast as a sorcerer of their level -2 (in this case 8) and I am having trouble selecting the spells, I've got

8 cantrips
5 level 1
3 level 2
2 level 3
1 level 4

Right now I am thinking on selecting
Level 1: Shield Nerveskitter, grease, true strike, silent image
Level 2: Wings of Cover, Mirror Image, knock
Level 3 Steeldance Vampiric touch
Level 4: Greater Invisibility

Assassin Spell Know
4 level 1:Sniper's Shot, ghost sound, Instant search, feather fall
3 level 2:Absorb weapon, alter self, undetectable aligment
2 level 3:Wraithstrike, non detection

So does anybody has good suggestions or comments concernig my spell selection
