Although changing out a headlamp was a simple task at one time, I have found it is much easier to have it done at a local service shop that does more than just change the oil. Look for one that does state inspections or minor repairs. They have the tools and the patience to do it right. The money you spend is worth the peace of mind!!

Replacing this type of headlight bulb should really be quite easy. The alignment won't be off unless the bulb was not installed properly.
Have a wonderful week!
