My Suggestion... listen to Ultima.... nuff Said.
Thanks Kham.

It's really all about preference and being comfortable. You gotta bring the right tools for the job at hand. I've seen some of the Asian players on my shard do some amazing things with just Vampire Embrace (20% Life Leech).
You have to experiment and find out what works best for you.
How about the general gameplay for killing monsters?
protection casted in vamp form most of the time. Which bosses should I be in wraith for?
basically
evade every 20 seconds
feint when not evading?
do I constantly have my wep cursed?
lightning strike every single hit?
I always wear "protection". For the Top Tier monsters like Rikktor, Dreadhorn, Mephsitus, or 160 Barding Difficulty you should use Lightning Strike on every swing. And keep Curse Weapon up...If your damage output is high enough some monsters you can get away with just 20% Leech.
Make sure you know your weapon and the monster your fighting. What is the monster's weakness or Achilles heel? This pays huge dividends.
You can choose to spam consecrate weapon when needed but it saps mana and it's time that could be spent using confidence or something else. And it's usually only good for 3 or 4 swings. So if possible make sure your wielding a weapon that is going to do the most damage to whatever it is your fighting. UOGuide has the majority of monsters...go find their weakness as this will help alot and determine if your using the right weapon and whether or not you need to use Consecrate Weapon.
I'm a Swordsman so I can't comment on Feint because I haven't used a leafblade against Top Tier Monsters. Now with Imbueing I plan on putting together a nice Daisho and testing it's limits.
I'm not sure if Evade and Feint are mutually exclusive (I think they are). I would go with Feint over evade. With Evade your not guaranteed to block..with evade you are guaranteed to receive less damage.
