A few quick tips to avoid some pitfalls along the way:
Cleanliness is of the utmost important, if it is going to touch (or come close to touching) any ingredient or the wort itself (don't forget about the funnels, spoons, measuring items, bottle caps, etc) it should be absolutely clean (one step cleaner works great and so does a water/bleach mixture). If you skip this step or don't get it right the result will be "Skunky" Beer.
The Mr. Beer instructions have you measure sugar into each bottle for the bottle conditioning. This method is fine (time consuming) as long as you get the measurements exact. If the measurement is off it can cause problems ex. too little sugar=lower alcohol content, less carbonation. too much sugar =higher alcohol content & exploding bottles (if you're using glass).
When filling bottles, invest in a wand system. It will make the bottle filling faster, easier, & give you just the right amount of headspace when the wand is removed.
Stainless steel brewpot, spoon, funnel, strainer, etc are excellent investments.
Have Fun!
