Hey man! For Dota items, everything you need to know (including poly counts) can be found on the Dota 2 Workshop info page here: http://www.dota2.com/workshop/requirements . You can find texture sizes and poly counts by clicking on any of the heroes available. The Art Guide, Texture Guide, and Shader Mask guide linked near the top are insanely helpful, I recommend reading those over!
Maya is actually what Valve uses so you’re in luck. Here’s a great tutorial by Lennyagony on how to model, texture, and import a Dota 2 item (although he uses 3ds Max for the modeling process) http://steamcommunity.com/sharedfiles/filedetails/?id=123397498
You can also check out some artist live streams for some insight on the process. Check out some of Anuxi’s here (click the videos button for recorded streams. Bonus: She uses Maya as well) : http://www.twitch.tv/Anuxinamoon
Anyway, I hope those are helpful! Good luck :)
