Contrary to what people think, you can have too much credit.
it's better to have 1-2 cards with higher limits, then a shitload of cards.
Inquiries on your credit Bureau aren't a good thing. Everytime you apply for a card, loan or any kind of credit (even a cell in some cases) it shows up as an inquiry on your Credit bureau. The only items that don't adhere to this rule are Houses and cars. They know you will shop these items, so they are only registered when a purchase is made.
You look bad when you apply for credit all over.
I have 1 CC with a 10K Limit and a line of Credit with a 10K limit. I completley fucked my Credit when i was younger with.....and wait for it....

I am just coming out of a Fiasco with an ex GF that Damaged my credit pretty good. for the last year I haven't bought a fuckin thing unless I have the cash.
Credit isn't repaired quickly. The first thing banks will look at is a Debt Serive ratio. How much you owe vs. How much you make. I forget what % they consider normal, but I beleive it's around the 40-50% range... I had a time 6 years ago when I was making payments on a condo, an M3 and a new Mini Cooper.. debt service ratio was over 100%.. and I was making good money at the time.
take it from someone who has been there... live well within your means, you will be happy later in life that you did.
