This page gives some information on Israel visas.
By comparison with other countries, Israel seems to be fairly laid-back about overstays.
Note that overstaying your allotted time elicits a fine of 135NIS per month – this can be sorted out at Ministry of the Interior offices or Ben-Gurion airport, but not at land borders. Travellers who overstay by just a few days report no hassles or fines.
However this doesn't necessarily mean it won't impact your actual visa. If you overstayed one time, they might think you will overstay again. I can't think of any reason why waiting would make this better - if your visa is ready for collection, go get it sorted out now.
