Sheesh! Questions, questions! I’ll take a stab at this seeing as noone else has, but bear in mind all answers are to be taken with a hefty pinch of salt and may not reflect the opinions of every Irish person, and no doubt somebody will be along in a minute to correct/contradict pretty much every answer.
How cold does it get there? Rarely below freezing, it hovers within a couple of degrees (C) of it for about three months of the year.
How warm? At the very most 32 degrees centigrade (90F I think), this summer was crap, I’d say 25 degrees C (80F) was about the best.
Do you get snow? At most once or twice a year, if that, and when we do get a lot we don’t really deal with it very well, busses stop running, taxi drivers go home, old people freeze.
Do the leaves change color in the fall? No we remove them for hygiene purposes. 
Do people drink alot of beer? I believe that Ireland is rated fifteenth in the world for alcohol consumption, but most people I know drink copious amounts of beer.
Do they drink it warm? Warm beer? Ick! Beer is drunk cold (maybe not as cold as in the US).
Is it true the ecomomy is picking up? The economy has been booming for about five years in an unprecedented way, mostly because of inward investment, and because of a young educated labour force, but underlying stuff is causing it to go a bit astray, if anything it’s peaked/peaking IMHO.
What are the households like? That’s a difficult one.
Are there many single mothers? Enough to go around.
Do people tend to stay married there? Up until a couple of years ago people HAD to stay married here. Divorce laws have been introduced, but are quite restrictive. Not that lots of people don’t get ‘separated’, or just stay unhappily married.
Do people have many children, or just one or two? Nowadays one or two. (I think we ignore the pope when it comes to contraception
Is there alot of crime? Our fair share, but violent crime bears no comparison to a country where anybody can walk into a shop and buy a gun.
What do you do with your old people? Do they go to seniors homes, or live with relatives? Both, depends on the old person.
What do poor people do for health care? Is there medicare or something? A national health service, which isn’t the best, or the worst.
Do alot of women work outside the home? There has been a big increase in this, it’s an integral part of the economic boom thing.
What is the education system like? Pretty good. Free education up to degree level, college entry based on a final national exam. (Though that doesn’t mean everybody can afford to send their kids to college though).
Do kids take alot of garbage classes, or do they stress the 3r’s? In school there’re very few garbage classes, though it is possible to take an extra year to do non-academic (is that what you mean by garbage?) courses. Mostly it’s stuff like mathematics, English, Irish, French, , other European languages, sciences (including evolution!), History, Geography, and erm, religion.
Do kids go to daycare there? or is there no need? Daycare? Kindergarten? Montessori? That kind of thing. Some do.
How pervasive is the conflict between the catholics and the protestants? is it only in the bigger centers? or all over? I’ll leave that one to another thread, probably in the pit.
What do Irish kids but at the store for a treat? Chocolates (candy), crisps (potato chips), Doritos (Doritos)
What do you watch on tv? American and British and Irish TV programmes (often, but not necessarily in that order).
What kind of card games do you play? Um, poker? Gin rummy? Bridge? Tell you what, you deal.
Dang just previewed and saw I was beaten to it, I’ll post this unedited anyway.
