Imperial Fist Army List ALPHA

I have Black Templars as my primary army so naturally when I decided to do a Codex Marine army I went with their founding chapter the Imperial Fists. The list below is a 2000 point list which I am going to use as my "to buy" list for my Imperial fists.

Eventually I will want to collect enough to make the entire 3rd Company, but I am going to buy the models for the list below as my starting point. I chose 2000 points because the majority of games around here are 1850-2000 points, so I figured to go to 2000 then I can subtract what I need to get to 1850.

OK so here is the list I am trying to build. Please feel free to critique it. I am trying to make a fluffy but competitive list.

So far I own 5 Tactical Squads, 1 Terminator squad, 2 full scout squads, a Devestator Squad, 2 Attack Bikes and Lysander. I am getting an Assault Terminator Squad as payment for a commission I did, so that will leave me mainly vehicles and a Librarian to purchase.

Well that is my list I am working towards. Please let me know what you think. I think it is pretty balanced and fluffy. I just need to figure out what to remove to get it down to 1850.
