Hm, didnt think its so important. After all, you all prefer to play your own chars, my saves are mostly for familiarizing yourselves with the game. But sure:
I've passed the first game as full-time paragon. That should answer all your questions. Kaiden killed, Ashley saved, Wrex is alive, romance is with Liara, Rachni queen is saved, colony of Feros is saved, Saren killed himself, let go Fist. Helped to bring in this Administrator on Noveria - dont remember the name... Yeah, its all Paragon.
And when I think about it, you are very right - ALL of it, every single thing has a great impact on Mass Effect 2 story and the characters you meet along the way. Some (very many) won't be there if you killed them - so I suggest you take paragon path in ME 1. You'll miss some NPCs and quests otherwise!
And when I think about it twice - you may even want to play with my saves. Some things are quite hard to achieve. Like quickly react to renegade or paragon actions, some doors will stay forever closed if failed to hack - some with NPCs behind them. So... In all, yeah. Consider it worth your while.
Second Game is passed as Paragon too. With an exception of cool renegade actions (tied to mouse buttons, not dialogues) like easing yourself fights. As breaking necks, throwing people out of windows, blowing them up... It's not really evil path, I believe, just when you have a chance to kick someone's ass before they start kicking yours, why not.
