I am also new to the responsive design realm. Something I have found very helpful with my own introduction into responsive web design is using the 1140 grid system. I downloaded from this site here… http://www.columnal.com/ Included in the download are css files for IE issue fixes that are ready for you to drop your own css in. Just as a side note, i had some issues understanding their files in the beginning an had to email them a question. They responded very quickly and were really helpful. Hope this helps you.
