DQOTD: 2010 Roth IRA Rollover?

[Midpack]

I've Googled but everything I find seems to assume I already know about this regulation and I don't. Some of them sound like in 2010, traditional IRA's can be rolled over into Roth IRA's regardless of AGI, with applicable taxes spread over 2011 and 2012. DW and I have two non-deductible TIRA's (so taxes would only be on gains?) and two Rollover IRA's between us (fully taxable, from previous employers 401k plans), that we'd probably want to turn into Roth IRA's. We are still both working and our AGI will most likely be above the AGI deductibility limits in 2010. So what are the options for us or is there a good resource showing the options? TIA...
