Hello
Since you have gotten a lot of positive suggestions so far I cannot add much more but I shall do my best. ^^
First of definitely go with Gyro Ball on your lead Forretress. Taunt leads are often frail and fast (eg. Aerodactyl) and Gyro Ball would be your best option here.
On Rotom go with Hidden Power (fighting) over Hydro Pump. You won't loose much coverage against the likes of Tyranitar and heatran but the higher PP and accuracy can benefit you.
Since you are using the standard (but underated) Torment Spiker Skarmory set I suggest you use the suggested EV spread: 252 HP, 240 Def, 16 Spe.
I have always found Starmie to be to frail to usilise a Choice Scarf so I suggest you'd go with the suggestion from MetaNita.
On Blissey I suggest Heal Bell somewhere, because stall teams in general don't like something like a poisoned Rotom or a Burned Hippowdon. I suggest it over Thunder Wave as with Toxic Spikes on the field and counters to every pokemon immune it's actually kind of redundant.
Hope this helped and good luck with the team.
