Starting my swarm

[wingedd20]

Greetings I have just started my Tyranid army and I am looking for advise working out what I want to run. I would like to run a mix between swarm and MC with a nice psyker presence. I want to make sure that every unit I run will work in harmony as part of my list as a whole.
My current plan for when I get to 2000 points looks something like this at the moment:

HQ Hive tyrant of some kind (if he walks i'll get some Tyrant Guard to run around with); Tervigon

Elite: two broods of 3 Zoanthroapes or more

Troop: Tervigon (one will have crushing claws toxin and adrenal glands as I already have that one put together); two broods of 20 Termagants(1 per tervigon); two broods of 10 Termagants(1 per zoanthrope); and a brood of about 20 Hormagaunts with toxin

Fast attack: If I make a flyrant I'll take a brood of 20 Gargoyles and a brood of 3 Shrikes

I want to have at least one unit of something in my list that can deal with heavy infantry like Terminators and Plague Marines. I don't know whats good for that but the few games I have played with my guard tell me that its something I want to have. It would also be nice have something in there that can surprise my opponent and shift the game in my favor. Something like a Trygon deep striking in would be a good example of this kind of thing. Powerful and difficult to predict until its changed how my opponent thought the battle was going. I would also like to have enough targets on the table that it be difficult for my opponent to deal with all of them. The idea is that if my opponent tries to effectively deal with one of my threats then he will be forced to ignore some of the others.
I already have a tervigon, 2 zoanthropes, 12 hormagants, 24 termagants, and a hive tyrent I am trying to figure out how I want to put together.
I forgot about biovores. I would like to try them out and maybe get some if they work well with what I have so far.

One: 3 shrikes is not enough. 5+ Bone swords and Lash whips. Two you are trying to do to much. Pick one and go with it, Swarm, + MC + Psyker= Not good at anything. Three: drop the hermis for more termis. This is something I have been figuring out, you really need to decide how you are going to hit your enemy: one huge swarm, or wave after wave of progressively stronger. Either Target saturation, or controling when where, and what happens.

Good good, OK so lets drop all the fast attack and the hermis add 3 more zoanthropes and about 60ish more Termagants. hmm so many questions. I suppose we could start with: I'm at point A, Biomass is at point B, I move from point A to B and the biomass stops moving. Or maybe: I have a tervigon 12 hormagonst 24 termagonts 2 zoanthropes and I just go the new hive tyrant kit, Now what?

You already have enough for sub-1k games, from my experience in starting an army I think you should get what you have assembled and painted before worrying about bigger lists so you can play. Playing will help you figure out what you want to run more than a forum will as we don't know your meta/playstyle and, if this is your first Nid army, neither do you. When I started building my army I was writing up 1850 lists and projecting so far into my armie's future that I really set back how long it would take for me to actually play. Get your Tervigon and some Gaunts/Zoans done for a 500 point list so you can jump into the game. After a few games with that you'll know how you'd like your Tyrant equipped, then you can get him done and move up to 750. After you play some 750, plan your next jump to 1k. This approach will get you playing and your army will evolve stronger as it'll be based off your meta and real experience, which a forum can add to but can't replace. Best of luck!
