Luckily there are a lot of new resources to help you prepare for Integrated Reasoning. Just keep in mind that the "main" portion of the GMAT remains unchanged and it is still the most important part of your GMAT experience.
Here are some links to some of the materials from Manhattan GMAT
that can help you prepare for Integrated Reasoning:
Free, Integrated Reasoning workshop video: http://vimeo.com/40520767

General IR info: http://www.manhattangmat.com/ir.cfm

You can also find some nice resources on mba.com. GMATPrep 2.0 has IR practice sections and the IR portion of OG13 is available online.
Hope that helps.
