first, thanks for so many answers.
DM changing isn´t an option(it´s the only dm i know).
The curious thing about the house rule of my dm(no xp for traps) is that sometimes put some very deadly trap that i have to disarm or similar but they don´t give me xp.
I don´t like the rangers cause my liking of rogue class is about his versatility and feeling of a thief or an assassin (i like this PrC but the req of being evil with my ~good party isn´t also an option).
I also had played a paladin, but my dm said if my god give me the spells and the dm is this god(in play) i can´t choose my spells, he give me the spells he wants(i nearly ever find an utility for a lot of bless water spells). So the hose of the rogue class isn´t unique. Maybe is only for me, cause i´m the more experienced player in the group and he wants to put me in hard time. I 've never understand why with random assignment of charges, in 5 fighters 3 go to attack the little rogue 1 the fighter and 1 the cleric.
Another time i´ve played a neutral cleric, that channels negative energy to use the inflict wounds(with another cleric & druid isn´t needed heals) but 5 ghost kill him in 1 round(they were 10 ghost in total

). I´ve to say that i´ve to convince him that with a primary spellcaster class the rule of the "GOD" giving me the spells he wants it isn´t very fair.
The melee cleric that you say seems interesting for me, thanks. But Oscar(my name is also oscar ) in what book is the contemplative PrC??, my dm also only let PrC from DMG and Faerun Books, and maybe some of the class books we have(tome and blood, defenders of the faith).. Divine disciple seems very good(why i´ve never seen this PrC???)." instintive attack from VofED" what book is this??. Mainly i´ve searched the list of spells from the PHB, what are the good cleric spells form the other books(they are too many spells for searching).
Without the special rule for rogues of my dm, what will be one good build for a rogue(mainly for combat, but rogues are very good for alot of things), and mainly i will want strategies for combat(or is only about flanking opponents??).
Why they aren´t character builds guides like in some videogames(diablo,dungeon siege...) in some aspects they are very similar of a tweaking of a d&d3 character. And they will be very appreciated for a novice powergamer like me.
I´m very happy for finding this forums, it´s alot of info there.
Thanks in advance.
