Rucksack size? Well, something about the size of a bodybag would be best, just leave it at the bottom of the North Face, and you'll soon be snug inside it, and getting carted back to the local morgue fairly quickly...
There's a picture with the route marked in the front cover of Joe Simpson's The Beckoning Silence. Don't bother reading the book, it's all full of boring history about the people who've been killed trying to climb the route, and it'll count as "beta", so you'll blow your onsight attempt.

At the moment doing it in rockshoes is as good as bet as any, just ignore any advice from the local guides who reckon that doing a summer attempt is suicidal because of the massive rockfalls, and you'll be fine.
Practice those dodging skills, and make sure you carry at least 20 spare helmets each, as dodging falling rocks will be the main worry. The climbing will be relatively easy, in comparison.
Don't bother with ropes, either. Rockfalls will only cut and damage them, and you might as well save the money to put towards your funeral expenses, once you've paid (well, the executor of your estate has paid) for the repatriation of the bits of your body.
Best of luck, anyway. I look forward to reading your obituary, probably titled something like:
Eiger Troll was actually serious. RT members shocked to find this idiot really meant to attempt the North Face of the Eiger, and posted advice in the - as it now seems - forlorn hope that he was taking the mickey.
Seventeen RT members are currently on bail, charged with aiding and abetting a suicide.
