Have a look at Traveline http://www.traveline.info/
It lets you enter start and end locations, date and start time, and will work out the best routes for you. Usually gives you 3 or 4 options, and shows total journey time, scheduled departure and arrival times for each leg of the journey, and any walking you may have to do (eg between bus stop and station).
The Bache station option suggested by McArthur Glen actually seems to be the slowest route at 1hr 38mins. The train to Conway St/No 1 bus seems to be one of the quickest at around 1hr 25 - 1hr 30 (depending on time of day). Another option suggested is train to Ellesmere Port then no.36 bus to the Oaks
