Jackalope swep

[DrVincentWolf]

I am working on a swep that will hopefully be used in a gamemode I am making. The swep is supposed to give the player a rabbit-head and horns. With the primary attack of the swep the player can cast ten small fireballs (or bullets, in the case of this wip) and with the secondary do a melee attack for a lot of damage.

SWEP.PrintName				= "Horn"
SWEP.Author					= "DrVincentWolf"
SWEP.Purpose				= "Press M1 for fireball and M2 for charge"
SWEP.Slot					= 0
SWEP.SlotPos				= 4
SWEP.Spawnable				= true

SWEP.Primary.Sound = Sound("Weapon_Deagle.Single")
SWEP.Primary.Recoil	= 50
SWEP.Primary.Damage	= 1000
SWEP.Primary.NumShots	= 1
SWEP.Primary.Cone	= 0.02
SWEP.Primary.Delay = 0.5

SWEP.Primary.ClipSize	= 10	// Size of a clip
SWEP.Primary.DefaultClip	= 10	// Default number of bullets in a clip
SWEP.Primary.Automatic	= false	// Automatic/Semi Auto
SWEP.Primary.Ammo	= "pistol"

SWEP.Secondary.ClipSize	= 1	// Size of a clip
SWEP.Secondary.DefaultClip	= 1	// Default number of bullets in a clip
SWEP.Secondary.Automatic	= false	// Automatic/Semi Auto
SWEP.Secondary.Ammo	= "pistol"

SWEP.ShellEffect	= "effect_mad_shell_pistol"	// "effect_mad_shell_pistol" or "effect_mad_shell_rifle" or "effect_mad_shell_shotgun"
SWEP.ShellDelay	= 0.05

SWEP.Pistol	= True
SWEP.Rifle	= false
SWEP.Shotgun	= false
SWEP.Sniper	= false

Now, I fully admit to being a lua noob and so I have used a lot of resources to put this together. Mainly:

My questions at present are:
1 How can I make the secondary attack only apply to melee range?
2 Currently my plan is to let the secondary attack recharge by prolonging the animation. Is this possible or is there a better way?
3 I want to change the way the swep is held in third person, how can I do that?
I will probably have more questions in the future but I want to get the ground-work down first.

Video for how the swep works now. Note that you don´t actually have to get closer for the second attack, I am just showing how I want it to work.
