New here and new to 'growing my own' veggies.
Had some success with my first attempts at growing potatoes and peas and
have been severely bitten by the 'homegrown' bug.

I am now considering getting a greenhouse to expand my veg choices and
allow for a longer growing season. After trawling through the pages and
pages of info on the web about greenhouses, I am even more confused then
when I started!

Can someone please enlighten me on a few points?

1 Which is best - horticultural glass, toughened glass or polycarbonate
panels?

Horticultural Glass has a green tint and is cheaper, Toughened Glass is
clearer and safer and dearer, Polycarbonate is clear, very safe but soft and
bendy so it scratches and gets pushed/sucked out in a gale. Your shout.

2 Is it necessary to have a base fitted to the bottom of the 'house'?

Always a good idea.

3 Can automatically opening vents be fitted to replace manual opening
ones without too much alteration?

Yes, highly recommended but do buy the best, cheap ones don't last long. Can
even have automatic opening louvers.

4 Is it good practice to line the house with insulation such as bubble
wrap?

Only if you want to keep stuff over winter, i.e. keep the frost out.

Another point is you need vents in the roof but also vent/s near the ground
so you get a throughput of fresh air, chimney effect. Normal to have a set
of louvers opposite the door at ground level but one either side works well
too.
