Ballybrit is on the east side of the city. In my opinion (no offence to anyone), the west side of Galway is the best place to live. I just find the east side industrial, rough and crammed with new celtic tiger housing estates. .
This is an amazing description of the East side of Galway. Hilsalt mentioned Renmore, a lovely family estate, houses well built, and would be considered large by todays sizes. Estate not too large, right near the water and easy to get into the city. Walkable to city center and there is a short cut if I remember along the railway line. Just down from Renmore is Wellpark, large detached houses to be found here. And closer to the city plus would be perfect to get to HP as you'd be going against traffic, my assumption is traffic is coming into city and you're husband would be going out. Tara Grove is another estate, more recently built, about 20 years ago I think. Then you have the option of the Tuam road, there are pockets of small estates there with a great location. And then on the Headford road you have a long established estate of Tirellan and Castleawn (some detached available here).
Don't let your husband do the bridge, life is not worth it. Traffic in Galway is cronic. Parking in the city really badly laid out. Don't know about schools. Anyone who lives on the Salthill side has to put up with all the summer trippers snaking along in the summer months heading out to Connemara. Personallly I think Knocknacarra is a large urban sprawl. Wouldn't be a fan of Ballybrit (which is where HP is) but that's a personal decision. It's been improved with new roads and the Dunnes stores complex and Clayton Hotel etc.
Big advantage to the East is you're on the Limerick/Dublin side. If you've plenty of money, large detached houses in the old Roscam, the new Roscam, recently built celtic tiger madness, nothing to say. The most exclusive part of Galway is Taylor's hill.
Oranmore is a lovely village, more a commuter town, with plenty of facilities and easy reach of the city. Beyond Oranmore is a nice part of Galway which is Maree, many large houses there and the sailing club close by. Behind Tirellan and hidden from view is a quaint village called Menlo, also on the water.
You haven't said budget etc. But for sure you must check out morning and evening traffic before you decide where to buy.
