Welcome Streaky. I'm one of those guys that really likes freebies so to find a good case for your T5, go to your local market and ask for a grocery bag. Not only will it hold your T5, there's room for your SD cards, wireless keyboard, sync cables, manuals and lunch. You will even have the option of paper or plastic.
As for the WiFi question, purchase a wireless router and attach it to your Datschunds ears. Hope this helps.
