What Do I Need?

I Just got Gmod with half life 2 and im kinda in a hurry to find out what tools and addons i need.

If someone could help or tell me, I would Very much appreaciate it.

General build:
PHX - standard building pack
Smartsnap - Creates grids on props when building
Stacker - stack props

Other
Wire mod - http://www.wiremod.com/

Spacebuild
Spacebuild Enhancement Project (SBEP)
Stargate
Gcombat
gm_new_worlds
sb_new_worlds2
sb_gooniverse

Divran’s thread will get you started on the basics of SVN which is a really useful tool for keeping PHX, wire and spacebuild model pack updated
