Home Theater Accessories Questions

[Bluray Freak 2009]

Hi Again Tomorrow Best buy is coming to install my Home Theater so the following questions below are just like questions about some Home Theater Accessories I bought and also some misc. Questions about some other topics like Sat Radio, and if I decide to purchase it an OTA TV Antenna the questions are below.

Here is the receiver I have It is a Denon AVR 4310ci FYI and the TV I have is a Samsung Led 8000 Series FYI

1. I bought the Harmony Remote Control and the lights in the living room are dimmers and are controlled manually by hand it also came with a small remote control to control them from the sofa and want to know if I can teach the Harmony Remote Control to control them as well so I only have to use one remote for everything is this possible?

Thanks For Your Help On Number 1 Guys I Checked the Harmony Website as some of you suggested and Yes I can control the lights with the remote.

2. My Receiver does Multi-Zone Features so I was wondering if I could have XM in the living room and Sirius in the Bedroom if my receiver has installation options for both Sat Radio Tuners.

3. My Receiver Comes with Indoor Antennas for the following Radios AM, FM, and HD Radio If I Buy an outdoor antenna for the Radios will I get more stations and better reception?

4. If My Satellite signal Leaves because of bad weather and I purchase an OTA TV Antenna will I get better reception and more Stations with an Indoor OTA TV Antenna or an Outdoor OTA TV Antenna?

Misc Question

1.I bought the Klipsch Sub-12 from Best buy but they stopped carrying it does anyone know if they will carry it again in the future Klipsch Still makes them but for some reason best buy decided not to carry them any more I wanted to buy a Second Sub-12 to put on the Left Side Of My HT?

Thanks Again For All Your Help And Advice I Could Not have done this on my own
