Buttons & icons wanted for new mobile gaming application

GameDay

mobile (smartphone & tablet) application that pushes out games to users

I need buttons and icons for various items throughout the app. Below is the name of each of the button/icon/tab and a brief description of what it is meant to capture:

Play - tab on bottom of app that enables user to play the game

My Games - tab on bottom of app that enables user to view which games he or she has played

Archive - tab on bottom of app that enables user to view library of all games offered thru the app

Friends - tab on bottom of app that enables user to view friends

Rewards - tab on bottom of app that enables user to view points/rewards/prizes earned thru the app

Play Again - button that enables user to replay the game

Download - button that enables user to download the game

Add to favorites - button that enables user to add game to favorites

Challenge - button that enables user to challenge another

Rating - simple (5 stars etc.) rating icon

Badges - a few simple badges that users can earn (a la Foursquare)

Offers - for this I need icon depictions of 4-6 specific offers w/ point totals associated with such offer. Example - icon showing 20% off Huggies diapers along with some indication that it costs, say, 1000 points to acquire such offer. Icons should show increasingly more 'expensive' offers, i.e., first icon offer = 500 points, second icon offer = 750 points, etc. So looking left to right the offers get more expensive and valuable.

We are looking for a fun and casual design that fits well with our logo and our target demographic - casual gamers (moms, etc.) Nothing too hardcore or overly 'gamey'. Please be creative!
