Hey we all started there and I think thats one of the biggest questions for beginners is how to condition, dye, and seal. Even very experienced people have trials and stuff to figure out better ways to do it.
What I would do is try and cut some scraps from your piece say from the edges where you know you cant really use it. Then experiment with it.
Try giving it some conditioner or a decent oil, let that soak in over night. Then try dying it, let that dry up then buff it out. After that you can seal it if you want with something like tan coat or similer. I like using sno-seal and it works pretty good.
Another thing is you can dye it, buff it out, then oil/condition it, then seal it with whatever.
Biggest thing in my experience is let it sit between steps for a good afternoon or day before proceeding to the next step.
