1500 pts Foot Slogging SW

[Bigthunda]

I know it's completely wack, but I already have half/mainly mechanized orks and chaos and am starting Space Wolves but I don't want to run a bunch or troop transports...anyways here's what I really want to run for 1500, please let me know how I can tweak the list and any tactics to use it more effectively =)
Troops:

Grey Hunters x10
Power fist
Plasma gun x2

Grey Hunters x10
Power fist
Plasma gun x2

Grey Hunters
Power fist
Flamer x2

Elites:

Wolf Guard Terminators x5
Chainfist
Power fist x2
Frost blade x2
Assault cannon

Lone Wolf
Wolf claws
Terminator armor
Melta bombs
Fenrisian wolves x2

Venerable dreadnought
Multi-melta
Wolftooth necklace
Drop pod

HQs:

Rune Priest
Terminator armor

Wolf Lord
Thunderwolf mount
Storm shield
Frost axe
Saga of the warrior borne
Runic armor
Fenreisian wolves x2


Basically the idea is to charge with everything....drop pod the Dread in to melta serious mech threats. The Rune Priest will hang back somewhere and snipe with Living Lightning for the most part (what other power should I take for this role?) And my wolf lord will be the serious charge ahead threat factor while my termies and troops slog forward to cover objectives and such.
