Yeah, you did OK for steelhead.
The MLa on the Okuma stands for medium-light action and correlates to the 6-12 lbs 1/4-1/2 oz., which means it's rated for 6-12 lb. line test and casting 1/4 oz to 1/2 oz weights.
The 40 on the Okuma reel indicates the spool size and how much line capacity it holds; the 40 correlates to 4000 size in Shimano reels. Some people might say that 40/4000 is a bit much for steelhead and that smaller 20 or 30/2000 or 3000 are better because they weigh less, but I think those people just need to workout more if their arm is fatigued from just a couple ounces

I use the 40/4000 for my steelheading and don't find issue with it.
Your rod length/action selection is a decent place to start with any of the techniques: hardware/float/drift. I will say that at one time, I was using a medium-light, 9'-6" rod for hardware, but some people here steered me toward using a similar rod, but shorter (8'-6") when my hookups were brief, with the fish coming quickly unbuttoned...they were right. When I made the switch, I started landing more when throwing hardware. If I were you, go ahead and start with what you have and see how it goes because I think you made a good choice to start with.
As you go, you will find certain rods are better suited for different angling techniques; I have a 10' for float, 8'-6" for hardware, 9' for drift, etc.
That 30 lb. Stren, which I'm going to guess is monofilament, is too heavy/stiff for the rod you have and I would switch that out...you can use 20-30 lb. on that rod if it's braid because it's a much smaller diameter and will not adversely affect casting, whereas I think the heavy mono might...or move down to 12 lb mono.
Also make sure to use a lighter leader than the main line, depending on conditions such as water clarity, water height, water temp, etc.
Overall, a good start...now grab some different main line and get out there! Good luck!
