DVD+R 4.7GB 1-16x speed - will it be read and can i burn it on...

As long as the disks are burnt at no faster than than 8X, it should be readable that speed. If you need faster speed for read support because the disks were burnt at a faster speed, then I would get an external burner that supports the faster speeds. Generally speaking you shouldn't burn disks at the maximum burn speed to avoid errors in burning. The specs say:
