To start with the last question: No, your choice of colour space doesn't have 
an effect on your RAW files.
And, You can use both with Digikam.  (that was easy ;) )

Now for the harder bit:

The main difference between the 2 colour spaces is that Adobe RGB has a larger 
gamut (can express more colours) than sRGB. BUT: most screens and printers can 
only use/display sRGB, so an image using Adobe RGB will not display/print 
correctly in such a case. At best you will get a transformation to sRGB 'on 
the fly', at worst your images will look very flat and dull.

If, like most people, you have your photos printed commercially, your best 
(only?) bet is to stick to sRGB. 

Only if you print your images yourself and you have a printer capable of 
printing Adobe RGB, you could study the differences and decide what to use.

The above is just a very quick answer, you'll need to search for more in-depth 
texts to really understand what's going on.
