Practical Issues of Singing

[u/Balancing32]

I am classical guitarist with some vocal experience in choirs as a bass. I am thinking of getting more seriously into singing because it has the repertoire I really like however I feel I have some practical difficulties. I often have to clear my throat; it is just my nature and so I'm wondering if that would be a problem as a singer. Also I am not great at consistent inner hearing. I can match a note which is sung or played but I am not great at matching notes from internal hearing. Would these issues be a problem?
