Older home theater system, Wii and new HDTV

[rhondor]

I just bought a Panasonic tcp55st30 plasma TV. Very nice! Its digital Audio out is Optical TOSLINK only.

I plan to use my existing Panasonic DVD home theater system, model SC-HT95, which is about 10 years old. It has composite and component but not HDMI or TOSLINK interfaces.

I get my TV signals OTA, not cable.

Few questions:

1. To connect from the TV to my home theater system I need to convert from the optical cable to dual (r/l) RCA connectors for the home theater. I believe I can use a product such as the Monoprice Digital Coax & Optical Toslink to R/L Stereo Audio Converter, . The TV manual says the digital audio out format is ""pcm/dolby digital, fiber optic". Would someone please confirm this is the type of product I need?

2. Wii connection. How do I connect the Wii to my home theater system?

Thanks.
