Remember to run lots of acid tests though, when doing LA for creatures 1+1 does not always equal 2. Like one of the posters above gave a list of pluses, very likely this is not a true total. For one reason the base hd of the race are treated as though they are as good as a level (for dragons this might be accurate to some degree, but not completely, they merely have some of the best hd around). For another when you get up into the +9 range it very well could be that it just isnt worth it in any way, shape or form.. I dont like choices to be easy, I prefer fairly even on both sides.. This means that it shouldnt swing too far either way, LA's of +9 tend to almost always be bad plans, small hd with a few impressive abilities leads to the Paper Tiger Syndrome.. they can hit but they cant take it.
Mainly just trying to say use some caution and test out a whole lot of different variables with various classes and situations. (in other words the formula you want isnt an easy and quick one, it takes time) I hope that it goes well for you!
