1)I know dropping back down level is the right thing to do but I still would have over 100 buy ins for the $1 level. Do I keep playing the $1 games till I get to the $300 and then play $3 games? If this is the right move what happens at $285 do I drop back down to $1 games?
it isn't either/or. You can take shots at the level you're looking to move up to; e.g. take $15 and use it for a 5-buyin shot at the $3 level. See how long it lasts (making it last isn't the goal though), and try to evaluate whether your game is good enough to move up / what you need to work on to be good enough. If you drop below $3, go back to $1 and work on what you've identified, then take another shot.
2) What is the best advice or rules to stop the bleeding on loosing days? I think I'm a wining player I just keep getting pooped on with set over set, stuff like that.
If you're playing well and losing because the cards are running bad, there's no need to stop playing unless it's affecting your ability to continue playing well. Some days, you just can't win. Those days aren't an issue if you're properly rolled. The tricky part is not fooling yourself that you're playing well when you're actually not.
And remember that "I'm a winning player" is not synonymous with either "I win every session" or "I'm a winning player when I play my B game".
3) Does any one use guide lines wen going into a session? Such as if you don't cash in the first 3 games don't play any more for a couple of hours/the day.
I don't. I quit asap when I feel I'm off my game, which can be for many different reasons from playing worse than my usual game to not being focused or interested enough. How much I've lost has never mattered because I don't play with money I'm unprepared to lose, both BR-wise and mentally / emotionally.
But that's me. Figure out what works for you, which may involve some trial and error.
4) Should I stick to one type of game only? SnGs/MTT or Cash/Ring games
For recreational players, I generally suggest playing whatever you feel like at any given time. I wouldn't mix game types at one time, but if you feel e.g. like playing some ring after finishing an MTT, enjoy.
Sure, some people will tell you it's better to focus on one type of game. But others will tell you it's beneficial to learn different games. Neither position is right for everyone; it depends on your individual goals.
