Tricker sends a TON of plants, so you should be in good shape. They tend to be very healthy, but not really "refined" growth. I really stuff my tanks full, and they are super stable. Don't be afraid to plant until you can't see 75-80% of the substrate, looking down from the top.
I have found that many plants go through a freak out period when they get moved. Whether it is from shipping or new tank parameters, or both, it is expected their will be some leaf die off. Just take the dying stuff off and wait it out, you will soon get new growth.
Planted Aquariums Central is my favorite online source for plants. Never lost a plant from him, and they all adapted quickly.
