1. Coming from someone who has run 3.5 and 4e campaigns, 4e definitely has some advantages. The classes are a lot more balanced and each is fun to play at all levels. It is also easier to run than 3.5 and the play is more smooth, less bogged down with rules, and allows for cinematic and flexible use of player actions (as long as your DM is willing to allow players to take part in crafting the game as they play, as D&D is designed.) Skill challenges are also a brilliant addition to the game.
2. DMing is a lot of work on its own without having players trying to add or mix systems that the game design can't really handle without serious modification. It's easy for a new DM or a DM with a new group to be overwhelmed and frustrated, and DM's should be having fun too. This isn't to say that the players shouldn't be creative or attempt things the DM isn't prepared for, but don't become aggressive or angry if an idea you have isn't fully implemented. As the DM become more comfortable with the group he's more likely to allow for more freedom and become more efficient at running unscripted encounters. If your DM is happy, the group is more likely to be happy as well. Don't go into the game with any ill will and it's likely to be much more enjoyable.
3. Without knowing what kind of point system you're using, it's hard to tell, but your stats seem rather overpowered compared to the norm. If this is a custom system where the DM is prepared for more powerful players and plans his encounters accordingly, more power to you. If this isn't the case, having an all-star character can drain the fun from other players, as they feel inferior to the "star" of the group; from the DM, as his planned encounters may become trivial and he'll be forced to scale up monster difficulty, which of course makes it harder for the rest of the group who isn't as powerful; and even for the player playing that character as they never really have to strategize or work as a team and have few weaknesses. I'm a big supporter of the point-buy system for 4e for these reasons.
With that rant out of the way, the D&D wizards of the coast website has a character builder that I believe is free to use for the first few levels that should help you with your character.
