Welcome to 68kmla 
That LC475 sounds nice
must have slipped past me in the couple of weeks i haven't been watching eBay,always looking out for those...
I do highly recommend recapping it anyway, after all it's better to get it done now than when it becomes a problem (even if they look good there not to be trusted!)
To get it connected to your PC your going want to find it a PDS Ethernet card, there where some for £10 - £15 on eaby not to long ago.
With the 1400 you could look into recelling the battery to get it back up and running, might also be worth leaving it on charge overnight, if i do that with mine i can sometimes get about half a hour or so's charge
