Sounds like you done really well there, not nice having to worry about a broken radio on your first solo nav - how ironic!
Burscough is an arse to find, especially in poor vis becasue the runway is like a grey-ish colour. I always look out for the big green water tower and the industrial estate, which the airfield is right next to. You can also use Ormskirk as a good marker as it's pretty much 2 or 3 miles north west of it.
My first nav solo was similar - from Liverpool to Leyland, accross to Southport Pier (clipping Warton zone) and back to Liverpool - it was horrible - so much to do in such little time/space. Warton were very good however and like I said before, if you can help them along with decent calls then they will do the same!
Good job
