but seriously...
as with almost everything, what is your budget? ...
as mentioned previously, you need a lot of practice and learning (especially with the questions you are asking) and you have to beg people to let you take photos of them... With what I read in this thread so far, I won't even let you take pics of my kids (nonexistent) playing in the back yard.
Beside Nikon/Canon, you might also look into Pentax. There are a lot of older lenses you can buy that is compatible, however, obvious nikon/canon occupy most of the market and if you are looking for the super telezoom lenses for sports etc, you don't really have much choice, but again, some how, I don't think you are really going to look for those. However, you can't do a wedding or any event with just the kit zoom lense... and also beware... most photographer has a few different cameras... I won't expect less than 2 on the photographer during a wedding with different lenses so they can capture the moment correctly.
Anyway, if you are serious, you need to look at cameras that are marketed as for serious hobbyist or semi-pro which will likely cost you 1k ish for the body/kit lense and a probably 2-3k later on for light/additional lenses and various accessories. but with a decent body with kit lenses, atleast you can start learning.
Also... you need to seriously learn photo processing if you are serious about this path... since you are asking about 1080 and pixels here, all I can say is good luck.
