I'm thinking that you're probably screwed if you go second... 3K points should have enough tricks that you'll get tabled when the Rhino dies turn one, no matter what you park it behind. You're PROBABLY safe if you get to go first and the Assault squads come down - 60 wounds with apothecaries takes some chewing through.
Overall, you're fast and can hit hard... so you've definitely got the Blood Angels feel in there. Might have an issue with some lists though - I can see Dreadnoughts giving you headaches as they'll probably try to get stuck in before your really good anti-vehicle arrives.
Ask not the Eldar a question, for they will give you three answers; all of which are true and horrifying to know.
