Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms first of all I would like to assure that that seems nothing very serious and you can very much relax.
Blood on spitting saliva that is also evident on brushing teeth is due to infection and inflammation of gums known as
GINGIVITIS leading to gum bleeding and for this you should consult an Oral Physcian and get evaluated and Scaling of the teeth and area around the gums followed by antibiotics, painkillers and gum paint can help in resolving infection and bleeding.
Nose bleeding that happened only once can be due to rupture of any small blood vessel which can occur due to trauma or injured vessel while nose picking and it is also not serious as it never happened again and needs no treatment..
The last part of your question is that red bumps in throat.
See, one bump n each side of the throat is present and it is a lymphoid structure known as
Tonsil and it is a normal structure and if it is not causing any discomfort it might not be swollen and due to
anxiety you are finding it abnormal..
But in case if it is swollen, consulting an ENT expert and getting evaluated and if the tonsils are infected antibiotics, anti-inflammatory medicine and warm saline gargles will relieve.

Hope this information helps..
Thanks and regards..
