Be sure to check out www.fedoranews.com
, they are a pretty new site, and have a (so far small) supply of help articles for new Fedora users.
If you have a good internet connection, you can use apt or yum to not only install new software, but to keep your system up-to-date. FedoraNEWS has help articles on both.

You won't use Samba on a dual-booting comptuer... Samba works across a network between two or more computers. Linux and Samba can't be running on the computer at the same time that Windows is running.
If you are only looking to share files between Windows and Linux on the single computer, you need a drive or partition that both Windows and Linux can read/write. Most people create a FAT32 partition, because it can be read/write accessed by both Windows and Linux. Otherwise, you can use a floppy drive, CD-burner, Zip drive, or USB memory drive to off-load the files in one OS, then load them on the other OS after rebooting.
