Upgrade of basic TV set up for Saorview/Freesat

Background
My current set up is a cheap as chips Beko 27" working off an attic UHF aerial getting resonable reception (incl TV3 & TG4) in West Clare. Yes, happy enough with just the 4 channels! I'll be turning the sod for a new house this spring so I'll be transferring any purchases I make to the new house (in 2 or 3 years time) and allowing for upgrading in the future.

What I'm considering getting
So I have to get Saorview and this got me doing research and I've hit upon the very open secret of Freesat. After a few hours/ nights research what I've come up with is this - an all in package that includes:

• dish
• combi box (ferguson 120)
• cable

Is there anything missing that will prevent me from getting up and running with Saorview & Freesat? Any other parts I'd need to get?

What I'm thinking for the future
Extra upgrades/ functionality I'll be looking for:

• A NAS harddrive for storing our music collection (currently 25GB). Currently its on the laptop and streaming wirelessly to a squeezebox radio which Santa brought for the OH;)
• Using this NAS hardrive/server for movies (is it possible to buy and download movies over the internet? I assume it is)
• Upgrade TV when ever the Beko gives up, or with the new house maybe get a second TV

What kind of TV should I be thinking of? Am I on the right track with what I'm thinking? Is there glaringly obvious stuff I'm missing?!!!
