alignment? buy the helms manual. all you need is a set of metric sockets (10mm,12mm,14mm,15mm,17mm) and you can pretty much do anything on a honda. you will learn from experience if its a small bolt, its a 10mm if its a big bolt its a 17mm lol. the alternator should be about 150 at autozone after core (bring in your old one and you get the core charge refunded).
I had never done anything on my car past oil changes and tune ups, but when my clutch went out and I did not have $575 to drop for the shop to do it, I bought a helms manual and did it myself. ~>$200 total. it took me a while, but after that I know my way around engines a LOT better and can pretty much do any maintenance required. read all of the steps over, and get under you car and physically figure out which parts are which and what bolts you will need to take out. trust me after you do some work on your car yourself you wont ever want somebody else touching it
