Remeber, all that follows is just my opinion, the main thing with this and any game is to enjoy it even if you loose in fact more so. loosing is nothing if you have fun doing it 
Venerable Dreadnaut
guess you're not planning on CC with this guy, for me, i'd go with the assault cannon or change to a plasma cannon (no overheat on a dread) drop the ML in favour of a heavy flamer and walk him towards the bad guys shooting along the way
6 Grey hunters
good solid choice if they're not moving
9 blood claws
1 wolf guard battle brother
not a fan of this setup, first of the WGBL can NOT join them if they use a drop pod i'd change them to mounted in a rhino and get rid of the flamer for a meltagun
6 wolf scouts
wolf guard
again, not a fan of this, i'd go with 6 scouts, 1 Plasma Pistol (PP) & power weapon (PW), 1 with PP & close combat weapon (CCW), 1 with bolt pistol (BP) & PW, 1 with a melta gun and 2 with BP & CCW, for 134pts this is my favourite setup add a WGL if you really feel you need to
5 long fangs
seems like you forgot a missile launcher, cost should be 188pts, personally, i'd drop them alltogether, see below..
8 blood claws
slow unit, if you drop the long fangs (LF), give these guys a rhino, an additional PW and a meltagun as well. Also, if you drop the LF you can get a landspeeder tornado as well
send the 2 units of blood claws in their rhinos up, hugging cover supporting each other, walk the dread up shooting at what he can, keep the Grey Hunters back shooting at whatever, get the scouts in behined should be able to take out a tank if it's there or whatever's hidding in the bad guys deployment zone and have the tornado zooming around the table like a fly on heat shooting at whatever it can see
However, like i said at the start, just my opinion feel free to disregard any and all of what i have said i wont be too hurt :O
