How do you deal with the gossiping parents, and the parents that want to take over as the Head Coach, and starts telling others that they are the Head Coach. When they only help out at times during practice, and some times at games when the head coach has to speak with the officials about the game.

Ouch..... why don't you give them a few tasks to do, take stats, do the book etc. There is nothing worse that parents undermining the head coach... you need to take control of the team right away.... don't let this go any further.

How many parents are you talking about?

Jobs you could ask them to do -
1- Stats
2- Scorebook
3- Film the game

Depends upon what type of team it is -- Rec. or Select. If it is a select team, you should make sure to choose the parents as well as the kids. If it is a rec. team, hand them the coaching card and enjoy the view from the stands.

One thing you need to do is have a short parent meeting to outline expectations. Most parents don't know squat about the team, the league, or even the sport. They have expectations that the team will win, when the reality is that the team was picked from a hat and you have little talent relative to other teams. They have expectations that you will babysit their kid and hang around while they are late to pick him up. They have expectations that they can come and go as they please without any notification to you. More likely than not, they won't know the rules of league (ie; no zone defenses, equal playing time, etc.) so you may want to point them out. The parents' role is simple -- get your kid to pracitce and games on time, ready to go, and cheer.

As for your specific situation, you may just have to talk to the offending parent. Good luck because any parent like that will just let it go in one ear and out the other. If he really wants to be the head coach, let him. Most will run like rats on sinking ship if offered. IMO, being an assistant is much better -- get to teach the kids the game and leave all the BS to the head coach. Good luck.
