Remembering a birthday is a nice gesture, and, is easy to do when the t has quick access to it in your file.

Some people are long, tight, huggers. If there is no cue from the huggee to let go, the hugger may hold on longer. In your case, not sure what you consider to be long. If it makes you uncomfortable, it should be addressed immediately.

I don't think either of these actions are "not normal" for some t's. My t is very affectionate towards me with her words and her touch and it's all completely appropriate, healthy, and natural. Can't say what is normal in your case without knowing what you consider to be lots of affection, how long the hugs are, what else is being said and done, the vibes you get from t with it, etc.
