OK, some questions from the "tapeless" newbie. My new HM700 should be here any day now and I hope you guys can help me with a few workflow issues.

1. Much of my work will be shooting short interviews with multiple subjects and then appropriate B-Roll. Is there some way to name and number the clips as I record to give me a clue as to which is Interview (and possibly who) and which is B-Roll for when I import into FCP?

2. If I want to re-use a card on a different shoot do I need to erase the previous files first? And how do I do that? Or...

3. Do I just record over the first footage? And if so, if the card was not completely full will it start the new clips at the end of the previous clips or will it record over the previous clips.

Thanks for any help you can give me.

In HM100 you can manually enter file name for each clip- that is while the card is in camera. I usually do it as I log the clips on import into FCP

If the card is not full you can just continue shooting. I usually try to store on HDD as soon as possible, so if the card fails my footage is on the drive. However I stopped doing it on location, get enough cards to shoot the whole day. Human error is the major factor and if the footage gets lost (which happens), it's mostly due to human error. So log your footage when you are not rushed.

3. Do I just record over the first footage? And if so, if the card was not completely full will it start the new clips at the end of the previous clips or will it record over the previous clips.

No it will not record over old clips. You can reformat your card in- camera through menu. I format not only clips, but also entire card. I also usually reset TC before a new project.

Manual is well written, so I would advise just read through it, so you know all the functions of the camera.
