questions on how to knit a vest

[Jaye]

Hi,

Hoping someone can help me with some questions. Want to knit a vest and had some questions before starting.

1. Armhole band. Need to p/u stitches - where on the armhole should I start?

2. Button hole. How will I know which technique to use even if I buy the buttons beforehand.

3. Left/Right front. When pattern refers to left front, for example, is that the left facing the garment or the left when wearing the garment?

4. Short row question. Not on the pattern, but would like to know. Do you start the short row on the same row that pattern calls for dec first 2 stitches?

Appreciate any help. As you can probably tell I am a new knitter.
