For the phones, don't bother with phone sockets - just wire everything with Cat5e or Cat6 and 'RJ45' sockets. You can either use adapters or cut the 'BT' plug off and fit an RJ45 plug to the phones. Doing it that way, when you change your mind (eg switching to VoIP phones) a few years down the line, you don't find yourself with "the wrong cable".
As to Cat5e or Cat6, well you'll get plenty of opinions. IMO there isn't a lot of advantage for a home sized network to Cat6 - but it's more expensive, bulkier, and harder to terminate. But Cat6 is more "future proof" IF it's installed correctly.
Where you run everything to, well that's simply a matter of what the building layout allows. You consider where you have room, and consider how hard (and long) the cable runs are, and go from there. If there is a choice of locations, then you choose the least difficult
Cable run lengths aren't generally an issue unless you have a very large house - you're allowed 90m between patch panel and wall socket.
