I would like to do a factory reset on my phone .will my iCloud make my contacts and information available again

A factory reset puts your phone back to the state it was in when you bought it. Your data won't be on there unless you restore a backup via iCloud or iTunes. If you've got your contacts syncing to iCloud, then they should be available to you again after the reset once you login to your iCloud.

Yes, after you've done resetting your iPhone to its factory settings, you will be met with the Welcome screen. When prompted, you can restore from a backup and have the device set exactly how it was when you created the backup or you can set it up as new. If you opt to set it up as new, all of your iCloud data will sync back to the device after you've configured iCloud on it.
