Broken Chainring & replacement advice

I did this yesterday!
Not sure whether I should get something different to replace so it doesn't happen again. Should this be a warrenty replacement on a bike thats only 2 months and less than a thousand miles old?
Can I fit other brand of chainrings on this chainset? Any advice? Its got a PCD of 110.
Would it be worth while to change the chainset to a Shimano 105 hollowtech one to match the rest of the 105 componentary? I assume I'd need a new BB as well?
Cheers.

The problem with the warrenty is that I bought it mail order, and need to get it fixed asap. I'll try going back to them and see what they say.
Any links for replacements please? I cant find any.
If you want to buy, here's a couple to start with

but yes, you'll want 50t 110BCD 5-bolt and any should fit
I emailed Giant and they replied telling me to take it to my local Giant dealer. So I did, who, slightly ashamedly I took advice from before buying mail order. They obviously remembered this, but were still good and are going to sort it out for me. Giant only cover the parts not labour, so I'm going to have to pay for that.
I admire your brass face. I don't think I could have done that after taking their time to get advice and then going elsewhere to spend my money.
I've never experienced nor heard of that sort of failure of a chain ring. It must be extremely rare - or manufacturers are taking weight saving a bit too far.

Damn, it even says "Powerglide" on it, that should probably read "Low Powerglide only!"
They phoned Giant quoting my frame number and Giant said that my bike was originally fitted with a triple and that either myself or the retailer had changed it for a double, saying no SCR 1.0's were fitted with a double.
My LBS reckon I got it so cheap because the retailer had stripped it of the triple for another bike. I know that my bike came from Giant with the double, as its the spring edition, and i've seen the same spec quoted on a few websites. So anyway, I phoned Ash Cycles who I bought it from, they said if I post the chainring to them they'll replace it under the warrenty. So I've got the bike back and the chainring is in the post.
