I have to disagree. Unfortunately, a lot of the spiders in BugGuide have not been identified by the palp or epigyne before being moved to a species page (not just salticids), so many of the ID's in there need to be double checked. A lot of them are probably wrong.
You can use Spiders of North America to determine the genus, and then use this site for diagnostic drawings (palp and epigyne) of many species:

Rabidosa sp. is a North American genus, so it's not found in Ireland.
Unless the mites are gigantic, yours is a small to medium-sized spider. Might be a Pardosa sp., but it's hard to tell from your pictures.
I agree with Rabidosa sp. R. rabida and R. punctulata are two species found in the area. R. rabida has some lighter-colored "indentations" along the inner edges of the dark brown stripe on the abdomen, faintly visible in this specimen, so that's what I think this probably is (in punctulata the...
It happens. Orb weavers are a more difficult group to work with than they often seem on the surface.
Anyway, if you ever want to check an ID for one of your painted spiders feel free to send me some adult specimens through the mail and I'll try to give you a reliable ID from the palp or...
The other pictures helped, thanks. Spider #2 is probably an A. diadematus, but not because it looks different from the picture you linked to. #2 has humps on the shoulders, which A. marmoreus doesn't have (couldn't see them in the first picture).
FWIW, here are some of the many other color...
According to the latest checklist for the Spiders of Canada (May, 2010), Araneus cavaticus isn't found in BC (In Canada that species is found only in ON, QB, NB, and NS), so this spider is something else.
Unless you've worked with a lot of these spiders and can recognize them as they appear...
If you really want to know what species you've got, take a few adult specimens to an arachnologist for identification (try a local university).
The genus is a little easier. From the pictures it is reasonably certain that you have a recluse spider, Loxosceles sp.. To confirm that get a good...
One species of Rabidosa has been found in Canada, R. rabida, and only in Ontario so far.
Your spider is a Pardosa of some kind, and probably P. distincta. It is very similar to an adult female P. distincta I have identified from Whitecourt:
Identifying wolf spiders to species based...
Picking it up by hand means letting the spider run onto your hand and sit there. I've handled hundreds of spiders this way and have never been bitten.
However, if you actually try to "pick up a spider," by grabbing its leg or its body with your fingers, it will usually bite you.
Nice pictures, John!
I have to nitpick on just one little point. :) There is no "i" in "Timarus." The correct spelling of the name is Tmarus rubrocinctus.

@Jack: You should post your blog link in the arachnology forum at BugGuide. I think a lot of people there would like to read your account and see the photos:

Looking forward to your macro pictures.
I was thinking Tibellus because of what I can see of the eyes. It would help if we had pictures of this specimen from other angles.
For comparison here's an adult female T. maritimus I collected last year (ID'd by the epigyne). I don't know what an immature T. maritimus looks like:
[edit...
That depends on the spider. Many "hibernate" or go dormant during the winter. Quite a few others stay active at ground level under thick coverings of snow. Snow is a good insulator. At ground level the temperature can be within a few degrees of freezing at the same time it is -30C above the...
