The best way is to watch videos..Read john palmer's book "How to brew" and try to find someone that brews to help you pick the right system. Experience is very helpful.
Considerations are 1) Are you brewing outside or inside? 2) how much beer do you want to make 3) Do you want to brew with extract or All grain. 4) how much $ do you want to spend for ease of brewing and higher chance to make better beer. 5) Why do you want to brew, occasional thing to make some decent beer to share with friend OR you really like beer and want play with recipes and craft it to your exact taste. How much effort do you want to put into a brew day (extracts are very easy. Just boil extract with water add hops at certain times, cool it down and add yeast. . All-grain requires holding grain at specific temps. Straining out the grain. Rinsing the grain and a few other steps.)
To answer your specific question about kits. Basically any kit will be fine. If you have a local homebrewing shop go there and ask them about what starter kit they suggest. You want a fermenter and fermentation lock bottle capper, bottle filler. hydrometer, and thermometer. They pretty much all come with those things.
For ingredients Start out with a beer "kit" where someone has measured out all the ingredients for you and has the correct yeast and hops and a recipe. Kits can be either 1)all grain (you'll need a few more pieces of equipment, highly suggest looking at BIAB (boil in a bag) system to significantly reduce the additional stuff you need) or 2) Partial boil kit (extract and some additional grains that you steep) 3) extract.
#1 is the most work and requires the most equipment but also is capable of making the best beer. Takes the longest time to complete 4-6hrs #2 much less work, makes pretty good beer and you just need a way to remove the grain sometimes the kits come with a bag that does this for you and it takes about 1/2 the time...#3 is the easiest..etc. All methods can make good beer although #1 makes the best however it's also more difficult and has higher risk to screw it up.
