My girlfriend got me an early x-mas present...

Well your fish are pretty new so just worry about getting them eating regularly. Later on if you want them to change their diet just dont feed them for a day and they should try just about anything.
 
I think people are really over the top when it comes to caring for Discus, i simply do 30-40% weekly waterchanges and try and clean as much gunk up as i can from the bottom, they just get fed like the regular fish do, some flakes in the morning and either flakes or bloodworm / dalphia at night and my discus are doing great.
