Across from Gotha. Drive past Olympia all the time. What you listed is all pretty easy. Save your self a buck, take your time and you can do all easily.
Haven't done an intake on this one yet, but they are usually pretty straight forward. Also pretty useless without other mods to justify the added intake like a chip.
Thunders should be pretty plug and play.
Chrome tips are a couple screws. Just get them straight.
Kidney grills are some clips. You need to remove a couple bolts to remove the cover over the radiator to get to them from behind.
Pedals are a couple screws or bolts depending on what type you get. Make sure they are secure and I'd use locktite so the threads don't loosen.
Taillights are a couple screws or bolts. Plug and play.
A novice should be able to do all the above in a morning. Give it a shot and if you have problems, post a question. It will probably save you a couple benjamins in the process.
