The key thing to remember and not to get too hung up over is that as has been said, the majority of the links will take months to get activated and then picked up by Google.
100 links is fine not bad there you could try a little more to be fair, just remember rome was not made in a day
Increasing your backlinks suddenly is not a good sign. If you must do that, then atleast 20% of the links hould be from high authority sites, preferable newsppaer... and don`t forget to mix teh anchor texts.. Whenevery going for link building campaign in a military style... do keep a budget for authority links.
Google spiders are fast.. they usually don`t show all index pages in their Current results... But the risk is not worth taking.
