Have you thought about Wallasey, New Brighton areas? Brilliant for both primary and secondary schools (Better results than some of the secondary grammar schools) plus the house prices are slightly lower than some of the places you have been looking.
I live in Wallasey, we have a few local shops in Liscard (although the actual shopping centre has become run down) but I would agree with those above who have said shopping is best left to the Oaks, L1 and sometimes Chester - or online of course ha ha
There is lots to do whether you drive or not, the transport system is great and the beach is within walking distance (New cinema, new restaurants, new STARBUCKS!)
The Wirral is one of those strange places where one road can be lovely and the very next can be a bit dire, it really does take looking around and talking to the locals - I'd suggest maybe renting for 6 months before you buy - You will get a good feel for the place that way and you'll know where you want to root down. But can I suggest if you do come to visit again you stay in the new Lodge in New Brighton - Its less than 12 months old and you will be able to see the other side of the Wirral - New Brighton has a good mix of the big old houses and the lovely modern buildings so you can have a good look around - Also take time out to discover the lovely little parts of the Wirral - such as Birkenhead Park (But not after dark!) and the Floral Pavillion for a show.
I love living here as I find it has just right amount of young and traditional - I can hop on a train/drive through the tunnel and I'm in Liverpool or I can walk to the beach and along the front, beautiful especially at this time of year to clear the cobwebs!
Moreton is a hard one I think - It used to be a very nice place, most people worked at the factory and worked hard for their children, my Mum grew up there and has worked hard her whole life, she has good qualifications and has since moved to Wallasey but - then the locals started growing up and moving out and the council started housing people who had to be rehomed from Birkenhead and everything went a bit downhill, there are still some lovely spots and if you would be willing to drive the distance you could get your children into a grammar/religious school out of Moreton but that would be up to you obviously. But places like Saughall Massey and the Millhouse Estate are very nice areas - Plus there is an amazing chippy on the corner by the little Tesco goes off topic
