need help front end fix

[jetblack_GT]

I wrecked my car a while ago and I am buying a front bumper cover, hood, front driver side fender, head light, and a couple other things, but I need to know if there is anything I need to know first like is their anything that is gonna set me back, or just the little pain in the a$$ things that will get in my way. If anyone has tips on anything that will make this a little easier on me it would be greatly appreciated.
