Wellll, your moves aren't too great. But I'll help with the EVs and IVs the best that I can! And unless you want them to be legit-looking, I wouldn't suggest maxing out every IV and EV point. Below are my suggestions if you want this team to look legit.
For Aggron, max out HP and Defense, then dump the rest of the EVs left into Attack. HP is mostly for Substitute.
For Blaziken, max out Attack and Speed so you can sweep and outrun many dangerous Poke'mon. By the way, what's Sleep Talk for? =3
For Salamence, Attack and Sp. Attack need to be maxed, then dump the leftovers into Speed.
Metagross, Attack and Sp. Attack should be maxed, then try to even out the leftovers into Speed and Defense.
Dusnoir needs max Speed and Defense. Then leftovers go into Sp. Attack.
Tyranitar max Attack and HP, then the rest can go into Speed HP mostly for Substitute..
Hope I helped a little bit. =)
For the best in IV help, I would suggest going to Serebii and looking at their IV calculator. http://www.serebii.net/games/iv-calcdp.shtml It can be difficult to see exactly how many IVs your Pokes should have. Once again, this is if you want this team to appear legit.
