please can anyone help/advise - as I'd like to keep my Omega going for another year or two and fear the worst!
Engine overheats when driving in town and hates being idle. Oil is leaking underneath and the garage wont touch it as its a suspected head gasket repair on top of that.... its a little old, but I love it! 
They don't leak OIL they just mark their spot.
Joke over. Oil leaks tend to be one of 3 things (or so I'm told by the massive amount of information in the guides)
The rocket cover gaskets leak, because the breather system gunks up and the crank case pressure has nowhere to go.
(due to cheap oil and short journeys and age)
Some oil filter housings leak (there is dispute about the best fix, but I fixed mine by going back the an earlier production standard.
They leak from crank position sensor and oil cooler pipe too - but less common.
They leak coolant for fun, hence so that might cause over heating, but also radiators block up so there's no cooling. I'm loosing coolant myself. Not much, but I top it up every week and it's going somewhere.
The reasons for a poor idle could be many things. Mine needed new coil packs, and the oil in the plug wells was mixing with water dripping from the scuttle creating a mayo under the coil pack.
Head gasket is often diagnosed because the oil filler cap often has mayo on it, which would suggest water in the oil. It's cheap oil, short journeys and condensation in most cases.
Someone will be along to ask you if this garage has done a compression test. Problem with that is that the plug holes are hard to get to, so a garage who can't be arsed is going to tell you the worst, and hope you go away.
I'd suggest a different garage to start with, but there might be a member nearby who can look closer for you
