That would be ad0,

and ad3. See §2.5 of the Handbook.

I don't think this is correct. See above.
You probably have ad0, ad1 and ad3. Those are the disks.
All disks can be devided into paritions, which FreeBSD calls slices.
Say that ad0 has only one partition. In that case you wouls see two
devices in /dev: ad0 and ad0s1. The first denotes the disk, the second a
partition on the disk, which you can mount as a filesystem.

You can leave the 3.5 GB unused during Windows installation.

No. FreeBSD's fdisk would see ad0s1 (your windows partition) and either
a lot of free space or ad0s2. In the first case you could use the free
space to create one or several FreeBSD clices, in the second case you
could delete the second partition or change its type.

The best way is to prepare the disk space _before_ installing FreeBSD,
e.g. by running parted from a bootable CD. BTW,
If you're going to muck around with partitions,
*be sure to backup all your important data*.
