As a homebrewer you're ultimately going to want brown beer bottles and caps or a kegging system to contain your finished product. There are many alternative options for the first time brewer. You can buy empty bottles and caps. You can reuse bottles and buy caps (not the twist-off cap bottles). If you're going to use regular pry-off cap bottles you're going to need a capper (included in starter kits) to press fit the caps on the bottles. You can reuse champagne bottles. You can reuse empty growlers from your local brew pub. You could use empty soda bottles and caps. In any case it's important to use something that will withstand pressure in the bottle resulting from carbonation. Again, sanitation is important. So, clean and sanitize the bottles prior to filling them. Soaking in a diluted bleach solution for 30 minutes and rinsing with clean tap water will do the trick.
I found when using PET bottles that you get a better seal if you take off the safety seal ring that is left after you opened the bottle the first time.
Keep your fermentation temperature between 22 and 28 degrees C for ale. Any higher and your beer will taste skanky, any lower and the fermentation process might take too long.
If it's too hot you can stand your fermenter in a tray of water and drape towels over the fermenter. The towels soak up the water and the water evaporates cooling the fermenter.
