I just set up my account today, and I loaded it with about 400 keywords, but gave it a low allowance per day.

So i got this warning on top:

Your account contains underperforming keywords that are slowing the delivery of your ads. Please take steps to improve your keywords and/or ads, then click the Restore Full Delivery button below to restore ad delivery across your entire account.

So Im wondering, should I ignore it, or remove 90% of the keywords?

I'd say just leave in the best-performing kinds of ads.

After all: what's the point of showing poorly performing adverts?

The thing about that.... is that I don't know which ones are good and which are bad. It shows the clicks and imporssions in the Campaign summary, but when I actually go into the Campaign, and view the Ad Groups all i see are 0s. The status of all the keywords in it is Moderate. :/

If the status of the keywords is "moderate" you're fine.
