If you have your camera set to Adobe RBG when shooting in Raw, I would think that you'd want to be working in RGB not sRGB in PS.
Actually, it doesn't make any difference to the RAW data produced by the camera, what color space you have set on the camera. It only effects the JPEG that the camera may produce for thumbnails, or an embedded JPEG in the RAW, for later extraction by the appropriate tool.
The other thing it effects, though, is the default way the RAW is converted, in a number of RAW tools. You can always override this selection, though, and develop your RAW image into whatever color space(s) the tool is capable of.
As to whether or not your Adobe working color space must match the image color space or not, that may depend on a great many factors (too many to go into here). But, at least for starters, and to avoid as much confusion as possible, you can either decide to:
1) Keep you PS working space in whatever you normally develop your RAW images to, and then convert to your web or print space (usually sRGB) near the end of your processing,
OR
2) Keep your PS working space in whatever your most used target space is (possibly sRGB), and convert your image to that space when you open (or not -- PS will keep track of what color space the image is in automatically, as long as it is properly tagged).
Some folks (for instance) like to temporarily convert their image into LAB representation, to make it easier to make luminance-only adjustments to the image, then convert it back into an RGB-mapped representation. Others will develop to ColorMatchRGB or some other really wide-gamut professional space, and do most of their work there, to avoid any funny clipping of colors or levels, until they are ready to 'purpose' their image for final output.
One important thing to do when working with color-managed workflows like PS and brethren, is to develop a digital workflow, write it down, and follow it (with appropriate modifications) until it becomes second nature. There are many good tutorials on developing standard workflows with standard tools. A couple of good sources might be: http://www.luminous-landscape.com
