When you export from LR3 make sure you select sRGB in the Files Setting / Color Space
In Photoshop CS5 under Edit / Color Settings set your Working Space as sRGB
In Adobe Camera Raw in Work Flow Options Set the Color Space to sRGB. (Work Flow Options = Link at the bottom of the Adobe Camera Raw Window)
Or if you use a wider gamut color space, I.e. Adobe RGB or ProPhoto RGB, Enable the Gamut Warning (Shift+Ctrl+Y) (or View / Gamut Warning). And then when save to Jpeg, you can use "Save for Web and Devices, select Embed Color Profile, and/or convert to sRGB..
The problem with editing in LR3 is that you do not have the option for Soft Proofing. In Photoshop you do have that option, and will be able to get a much better idea of how an image will look on your monitor and when printed or using a different color profile. (View / Proof Set up). You should also enable the gamut warning while editing in a higher gamut color space..
