If you buy the Character Revival, everything on your character is restored, as it was before it had been deleted; including PvP rank, items, armour etc.
The item costs 7.5K AP and instructions on what to write in the ticket once you have purchased are clear on the item. Please do remember to not take it out of your bank! =)
I hope this clears up any worries you had, if you need any more information, then please just let me know =)
