Not every port is of equal blockade value. You are probably better off blocking some of the Texas ports before some of the East Coast ones, as their value is higher. The values are posted over in the "Blockade System explained" thread. Some ports, if l, for anyone who hasn't seen it. Also, if left open some ports actually lower Blockade percentage.
[Note: Missed the part where OP said the squadrons were filled out]. In the 1861 scenario, some of the free blockade squadrons, some of the brig units, and some of the frigate units the Union player receives are not all fully-strength ed when they appear on the map. Even if these are still locked, you can put the ones in port in passive mode and they should start to fill out as long as you have enough replacements on hand. I always make sure to separate them from the rest of their original stack, since they will likely be under construction by the time the fleet is able to move. In this way you can get a bit stronger navy without sinking in any additional resources.
Regarding ironclads, Confederate Athena tends to build quite a few of them. So if you are playing the AI, I would have a couple handy by spring 1863 but more so on the Atlantic coastline to help protect blockade fleets at major ports. Ironclads can be are more annoying than devastating when it comes to trying to hold a blockade in place though, so it might not be worth the resource sink.
