Nice list, and welcome to Heresy. Outflankey armies are undoubtedly fun, and stealers with broodlords coming into a unit of something reasonably shooty is just fun. Today, I felt that experience of fun when I outflanked 8 stealers and a broodlord. Into 9 grey hunters. The mess was unbelievable.
Anyway, first thing to do is to find some points from somewhere. Once done, remove scything talons from the stealers and give them (with the exception of the broodlord) toxins. Then, against MEqs, you've got 4+ wounding with rerolls. More to wound rolls made = more rends = more kills. Against TEqs and GEqs you're doing about as well or better. Then you also kill MCs better. It's just full of win.
Warrior loadout is good, but the number may not be. I haven't played enough high-point matches with warriors yet, but I've always played as 3 or 4. People do say that any more than 6 (the prime puts it to this) is too cumbersome, less than 4 is too fragile. Possibly reduce them? Also, not sure about this though, the FAQ has said that Primes/ICs can't join a unit in outflanking unless it already can. Technically separate units, so the prime would have to go without outflanking.
Screamer-killer Fexes aren't very good, I feel. Due to the unpredictability of scatter and the range of Bio-Plasma, it wouldn't be used much. It is nearly in charge range, but it does have the upside of nearly ignoring the fex's awful BS. Maybe take a dakkafex (2 sets of TL Brainleech Devourers, 190 points total for the fex)? It's one of the only two loadouts said to work.
Then there's the opinionated question of the Flyrant (winged tyrant, not sure how new you are to Heresy/40K forums). It's the right upgrade for a choppy Tyrant, but it does leave him useless when he DSes.
And if you're going for a full-reserves list, either scrape 40 points together for a pod for the zoan, or drop it entirely. It would attract every long-range weapon on the board alone, and would do absolutely zero good.
