We have got a rift guide from RIFT Power Leveling Tips I, in that page you will get some rift powerleveling guide for Rifts and Invasions, below are some tips foe PvP combat and Dungeons.

PvP combat
If you enjoy PvP combat, note that there are PvP dailies you can do each day which provide a good amount of experience points. The truth is that PvP itself does provide a decent amount of experience points (less than questing, but still well) when combined with the daily quests, you are certainly can get a large amount of XP.

Dungeons
For RIFT Power Leveling, once you hit level 17, you will get the option to access a variety of dungeons. These dungeons are for 5-man groups and feature powerful enemies who drop good rewards (RIFT Platinum and armors).
When you do a dungeon for the first time, there are generally a few quests you can get which make it very worthwhile. Such as Realm of the Fae has three quests associated with it, one of which provides a great weapon reward. While it may take you 30 or 45 minutes to run through, you can get a full level between XP from the monsters and the quests.
As a result, you always want to run each dungeon one time in order to complete the quests. Dungeons can also be a good source of faction if you are close to reaching the next level of faction.
As it said, doing dungeons repeatedly for loot (prior to 50) is a waste of time. When you are leveling up, you are going so fast that you are constantly replacing your gear. Do not waste your time going over the same dungeon repeatedly hoping for armor or rift plat drop.
