The dragon was only available to players who purchased the collectors edition, ($80.00) however, I have seen many of the little guys put up for adoption. Check the sales board on your server and see if there is one that you'd like to bring home...
As of last night, there were about 6 up for sale and depending on prefered color, price on my server, (Toxxulia), ranged from 2.5 plat to upwards of 20 plat from various sellers.
I don't know for sure about the D'Lere statue, (I'm in Qeynos), but statues of the queen are available for purchase and could also have been a perk of the collectors package.
The queen's statues tend to cost much less then a dragon. Last night I saw about 15 or 20 for sale and they averaged around 20 gold.
