First of all hello, I'm new both here and to Epic Armageddon

After playing a few introductory games with my friend who's the only other Epic player so far (and as new as me) I'm trying to make a semi-permanent list that I could focus playing with and know what to paint first as I've collected a lot of stuff off ebay - but am a notoriously slow painter. Since I'm creating a Flesh Tearers army, I'm using Blood Angels list, specifically the 2.02 revision of it which as far as I understand is the latest one.
The list looks like this:
Grunts (39%)
Terminator detachment + Supreme Commander @ 450
Tactical detachment + 2 Predators Destructors @ 425
Tactical detachment @ 300
Fast Attack (36%)
Death Company x4 @ 325
Assault detachment + 2 Bikes @ 275
Assault detachment + 2 Bikes @ 275
Bike detachment (all Bikes) @ 200
Support (25%)
Devastator detachment + 2 dreadnoughts (PF/AC) @ 350
Thunderhawk gunship @ 200
Thunderhawk gunship @ 200
TOTAL: 3000
Now what I understand that I lack is AA capability but I don't think my friend has any aircraft in either of his armies so Hunters would be kind of a waste and I don't have any models either so will probably have to convert them. I figure I could probably do with a landed Thunderhawk in a pinch for light AA anyway.
Speaking of Thunderhawks I have 2 more (all of them old school shoeboxes that I happen to really love the look of) so I could add more but again don't want to cheese out too much before my friend learns to build a more balanced army too.
I'm also going to want to add a Warlord titan once my Imperator model gets here ^_^ Is it a good idea to use it at 3000 points or should I build a 4000 point army for that?
