I'm new to video editing myself, I've been making short clips with a digital photo camera and have only recently bought a miniDV cam from ebay
If you get your footage from a (mini)DV camera, you definitely want Kino, it's just great. It can deinterlace and add a few effects, enough for the quick edit, you know, cut what you don't need and stuff. Just get it anyway.
If you would like some more fun take a look at Cinelerra (be sure to use the community version, not the heroine one), it does crash a lot (A LOT!) but it recovers nicely. It's often criticized for it's complicated interface but I'm a total n00b and it works just fine for me, add video tracks start mixing.
I didn't check out Lives yet but I will soon.
