you can target any market you want.

 

I think the best way is countrycode.domain.com as in example #1 because the PR will be easier to improve.

 

Targeting geographically is done with a few different methods, below is a list of them.

1. Using CC-TLDs (country-coded domain extensions)
2. Hosting Geograhically (Hosting in the country\region you want to rank in)
3. Local Language (Using the country\regional language for your content)
4. Geo-Targeting inside Google Webmasters Central
5. Building backlinks from that geographical area.

Now, you don't need to do all of them, but the more the merrier.

 

and also, targeting a geographical keywords

 

how about the simple solution?
Google Webmaster Central : GeoLocation

 

I'd go with the simplest solution and start with a .com domain using Google Webmasters tool to target a region. Whatever you do don't start with a country specific domain extension, e.g. .co.uk, or you'll make it difficult to target other countries in the future.
