I'll ask the heroes if they want/mind having their stats printed up (actually, Sir Anton's player posts on this thread and has his sheet, so he can post Sir Anton's stats if he wants to).
As for villains, well, not to spoil the illusion too much, but I pull them staight out of my a...I mean, out of the relevant books (Monster Manual for some monsters, DMG Generic NPC's, Legends of Excalibur: Arthurian Adventures for Monsters and Generic NPCs), using average hp. When I pick extra feats, I use toughness unless I have a reason not to. Easy to remember and adds a little bite to the minor villains, and it also means that the pc's are a little "better" than their npc contemporaries. Also, sometimes, I don't stat out the villains at all, but eyeball it (the younger "nun" had no stats, I just figured what spells she would have, and then given the party's suddenly increased resources (new Minstral with wand of faerie fire (grrr), new Hedge Mage), reasoned that she would have a chance of failing to escape. Then I gave hera level, hp and AC on the spot. And lo, she failed to escape! But she got better...

). Roderick is a great villain-to-be, but has no stats whatsoever, yet. I just knew he was tougher than the (damaged) Sir Andrew in the joust, and that his sister Brigit is tougher than he. One of the players has wondered how Brigit could have lost to the Giant Gotch in the meelee part of the joust. And they might find out why later, if they go to Baron Ivo's again.
Sir Lucius is another example. I knew that he was tougher than Sir Caius, but when he had the mind of a wolf man, I just use wolf man stats, with higher BAB and more HP. And because I didn't want to "Mary Sue" a character, but keep the spotlight on the pc's, I made sure the hag targeted the cured Lucius with something that incapacitated him for the battle (costing her an action), and Hobb (at the time) was useless in combat, but only good for healing.
Now Hobb (and Hubert) have stats as cohorts, but I had the players roll them and equip them.
I cannot overemphasize how much of a lazy DM I am. It is my second defining trait (my first being my lousy dice luck). Luckily, I have some small skill in improvising, and I have an idea of some critical events that are happening.
Partly this is because the party is advancing and moving around so much, that I don't want to put stats on a villain that will end up being either not encountered at all, or too weak compared to the party by the time the party encounters it.
Also, I don't bother to stat out noncombatants. Priests they encounter just heal them. Commoners talk to them. Etc.
The elder nun I worked backwards from. I figured what she was doing was something like Dominate. And she could heal, so that puts her at Priest 1/Hedge Mage 9 at least. And that is as far as I got. But since Sir Caius assassinated her while she was sleeping, and she had to make a fort save of 31, and rolled low, I didn't worry about statting her up. Good thing too; I would hate to have wasted that time.
Mind you, King Anguish is going to pay (in reputation, if nothing else) for allowing an honoured guest to be murdered in his own castle, but that is a social problem for the players.
And some of the megavillains already have stats in the text legends of excalibur: arthurian adventures, but currently they are in the "pulling strings and giving off a nice reputation" mode, so the party isn't going to fight them...yet.
I mean, the main NPCs (Arthur, Merlin, Morgan le Fey, etc.) are about 20th-30th level!!!! Good GOD! How could the party even hope to not be outclassed by the heroes, or decimated by the villains! So, I don't use those guys yet. And I do advance the party fairly quickly.
This is also why I give all spellcasters spontaneous access to all spells. It gives ME a break in preparation of villains, as I can just pick them out of the book on the fly (the players can too, so it is fair).
Now I may stat out villains later when/if it becomes likely the party will stick around for a while. But it is largely after the fact, so sorry I couldn't help you there.
