Starting with Blood Angels then:
Librarian is fine, provides some nice Psychic defence and the like as well as being able to get to where he's needed.
I don't like BA Tactical Squads. I think the writes are trying to make you take Assault squads by simply making them much better. Unless your collect is not permitting, I strongly advise that you turn those tactical marines into assault marines. Perhaps consider:
9 Assault Marines (remove jump pack); Powerfist, Meltagun, Rhino
That way you get a solid assault element which can be supported by the Grey Hunters.
As for the scouts, I'd rather take a Sanguinary Priest with some power weapon or other; I consider a fist quite risky on a one wound Independent Character, so perhaps going for a Claw might not be too bad a choice in this situation. That also comes out 20 points cheaper than the Scouts. He can hop in the Rhino with the Assault Marines and give them some pretty epic FNP cheesiness. :D
As for the Landspeeder, although it's yet another change to your list, I think the Assault Cannon is massively overpriced for what it does. For those points I'd be tempted, personally, to take a Typhoon Missile Launcher instead, and then sit back and pop transports. Unfortunately though, to do that, you've got to be pretty stationary (6" movement), which forgoes your greatest defence in Skimmers Moving Fast.
Another option would be to give it a pair of Multimeltas for tank-popping-goodness.
Now for Space Wolves:
Wolf Priest is fine. I'm personally more partial to the Rune Priest, but with a Librarian in the combined force, I think you're set for Psychic defence as it is. A Rune Priest would offer you a chance to get Jaws of The World Wolf into your list, which is particularly appealing. That said, Oath of War isn't too shabby either.
Wolf Guard are nice, they offer loads of opportunities for customisation, which I see you've capitalised on. Personally, I'd field a forth, in power armour, with a power fist. He could be joined to your Grey Hunters for a stronger CC kick as well as a leadership boost. A Wolf Guad with a Power fist is 38pts, and has 2 attacks; a Grey Hunter with a Power Fist is 40 pts and has 1 attack. Seems a no brainer to me. That said, it would mean you'd have to drop a Plasma Gun from your Hunters, as the squad size drops below 10.
Hunters look good, I've already mentioned my thoughts on the Power fist guy, and how that would affect the second Plasmagun. I'm more a fan of Melta on these infantry squads (as you may have noticed ;)) so perhaps swapping out the Plasmagun for a Meltagun could be a good idea (assuming you drop the squad down to 9 men for that wolf guard). The remaining 5 points could then give the Wolf Guard a Combi-melta for a bit more anti-tank in a single shooting phase.
Apologies for the number of alterations I've suggested - I know that often, the models won't be available for these sorts of changes for a list, but they are, in my opinion, the alterations which would make the lists as strong as they could be.
So what I'd take:
- Sanguine Sword, Wings of Sanguinus, Jump Pack. 
9 Assault Marines remove jump packs
- Meltagun, Power Fist, Rhino 
- Lightning Claw, Infernus Pistol 
- 2 Multimeltas 
A little different from what I orginally suggested to make up the points, but the thoughts there still stand. (perhaps you might want to rework the last 40 points (the Jump Pack and Infernus Pistol) a little bit o suit your liking)
- Terminator Armour 
4 Wolf Guard
- Terminator Armour, Storm Shield, Thunder Hammer
- Terminator Armour, Pair of Wolf Claws
- Terminator Armour, Chainfist
- Power Armour, Power Fist, Combi-melta
9 Grey Hunters
- Meltagun, Rhino 
Hope that helps you a little.
