Yes, you can use PVC for the ports. Just make sure it is the correct demensions.

You can also make it vented. but thats more difficult for your first box.

A vent is a port and a port is a vent. If you are thinking there is a difference based on shape, don't. They two terms are the same.

Port length is determined by a couple of things. The port area, the volume of the enclosure, and the tuning freq. More volume of displacement from the driver requires more port area. A small box will always require a longer port thn a larger box, all else being equal.
