The easiest way to install apps2sd is by using G.O.T's OpenRecovery which you can find here
. But to use G.O.T's OpenRecovery, you need to flash the vulnerable recovery first.
Since you used Easy Root to root your phone, I am assuming you didn't feel comfortable flashing the vulnerable recovery. Otherwise you wouldn't need Easy Root, since you can also root your phone using G.O.T's OpenRecovery after you flash the vulnerable recovery. Have a look at this this screenshot
And if this is the fast and light telus rom
you are talking about, I am afraid you wont be able to use that either without flashing the vulnerable recovery. Its a nandroid backup and you need OpenRecovery or ADBRecovery to "restore" it to your phone.
