Best way to check your speed is to either ask sky or check online. I've seen Fibre speeds of 80 Meg and less than 5 Meg so it varies.
As Sky Fibre is now 'self setup' there's no reason why you can't just leave it the way it is. You may not get the full speed unless you're in the master socket, but if your line can support more than 38 then you'll likely get the full 38. Actually more like 40. 38 is the advertised speed.
