game mechanics: Number of attacks?

[Madscientist]

I am confused when I was reading the rules.
It is easy when you have a humanoid character with weapons equipped:
- As a standart action you can make one attack with the weapon in your main hand
- As a full round action you can make several attacks per round, e.g. having high BAB and maybe having a weapon in each hand and the two weapon fighting feats

Now I have read that some characters can learn other forms of attacks, like having wings that can be used for attacks or getting a bite attack or something else.
How many attacks do you have then if you perform a standart or full round attack action?
I guess if you get claws they replace your hands and you cannot use their weapons anymore.
I ask because I want to make an aasimar paladin. I have read they can grow wings. I think it would be cool RP wise, but if they have an effect it would be even better.

What happens if you come from the other side.
I know summoner is not in the game but I ask anyway. I have read that creatures do not gain additional attacks via high BAB but only by having several body parts they can attack with. But your summon can grow arms and learn to equip weapons. Does a creature suddenly become a character when they equip weapons and the rules for attacks change?

Generally speaking, what defines if something is a creature or a character?
It looks like it does not depend on if this something uses weapons/armor or only natural attacks.

Normal weapon attacks depend on your bab (base attack bonus) every 6 bab you get one more attack starting with 1bab.

So for example a fighter lvl 6 has 2 attacks with bab bonus of +6/+1


Now there are NATURAL weapon attacks there number does not depend on there bab just simple on there number and if there are primary or secondary attacks (bites are as far as i remember normaly primary and wing attacks for example are normaly secondary)

Primary attacks get full bab and i am not sure anymore full strength bonus.
Secondarys get (without feats) a malus of -5 and only halve str bonus.

So for example a dragon with a bite, 2claws, 2 wings and a tail would attack with all of them every round(as a full round action of course).

2 weapon fighting i have never done but it as far as i remember works kinda like a mix between the two where your second weapon becomes a secondary attack.

You can mix weapon and natural attacks but all natural attacks become secondary attacks (after your normal weapon attacks) and you can not attack again for example with the same arm/claw you would hold your weapon (simple logic).

2 weapon fighting basically (if you have the feat, and take the right kind of weapon) gives you a modifier of -2 to all your attacks, but you get a single extra attack at max attack modifier (-2) with the weapon in the off-hand.

As soon as your BAB reaches +6, you can get improved two weapon fighting feat which grants another attack (-5) in the off hand.

As soon as your BAB reaches +6, you can get greater two weapon fighting feat which grants third attack (-10) in the off hand.

E.g.
Lets say a lvl 20 fighter has an attack bonus of +37.
hand1: +37/+32/+27/+22 attack bonus
hand2: shield

If you have the feat two weapon fighting and a light weapon in off hand:
hand1: +35/+30/+25/+20 attack bonus
hand2: +35 attack bonus

If you have the feat two weapon fighting, improved two-weapon fighting and a light weapon in off hand:
hand1: +35/+30/+25/+20 attack bonus
hand2: +35/+30 attack bonus

If you have the feat two weapon fighting, improved two-weapon fighting, greater two-weapon fighting and a light weapon in off hand:
hand1: +35/+30/+25/+20 attack bonus
hand2: +35/+30/+25 attack bonus
