Hi Jane and welcome to the board!
First and foremost, I've never heard of a completely dumb question. The only thing I see is people with different levels of knowledge. But at some point, everyone had to start learning. So feel free to ask your questions. Now for some answers:
The first few questions are about the memory card. I have the card in my camera right now, there are 10 pictures on it. Can I remove the card and transfer these pics, or, do I need to wait until the card is full before transferring? If the card is removed can I replace it after the transfer?
The card is a completely different thing from a ASA film, which I'm guessing you're more familiar with. The card stores pictures one at a time, but a picture in digital photography is just a file, like a Word document or a MP3. And the card acts in much the same way as a floppy disk. So you can remove it anytime (except when the camera is saving data, of course...). You can transfer your pics anytime, erase one of them, put the card back in the camera, etc, all this anytime you want. You can erase all the pictures on your card, or format the card, and it's like a new one, empty and ready to receive new data.
This is actually one of the main advantages of digital photography, you don't have to restrain yourself since you don't have to worry about taking many pictures like with film. Shoot hundreds of pictures, experiment, and only print the pictures you prefer.
Also, if the card is in the camera, can I transfer with the usb port, or do I need to remove the card and transfer with it?
You can transfer data with the USB cable that probably came with your camera. Sometimes you have to install the software that came with the camera, sometimes the camera simply acts like a card reader that appears in the "My Computer" menu.
In any case, always COPY the files to your computer, do not MOVE them. This ensures that if the transfer goes wrong for any reason, you don't loose your pictures. After the transfer is done, delete the files with the card in the camera, or format your card.
The camera is a Kodak Easyshare, if that makes any difference.
If I remember well, it means the software will take care of the transfer for you if you plug the camera in the USB port. If you do so, just make sure your batteries are not near the end of their cycle, so that the power doesn't fail during the transfer.
I hope this helped you. I strongly advise you to visit the Glossary section of this website, and then to look at all the items in the left-side menu. You can read everything that's there at your leisure, and you will probably find many useful tips and bits of information.
Feel free to ask more questions.
