Too much credit?

I need some advice... I've spent the last year cleaning up my credit (420 Fico now up to low 700's) and I now have all the credit and credit cards I want. I need to know if I have too much credit, and if I should close some of these cards, or if I should just leave it be. Here's what I have:

Capital One - Opened in 1999. 300 limit, they won't raise my limit. I haven't used this card in almost one year. Completely sock drawer. High APR (I can't remember exactly, I think it's 19% since it was my first CC). No rewards/benefits/etc.

Chase Classic - Opened in 2001. They just upped my limit to 2000 bucks, I was somewhat pleased. The APR on this card is 18%. No benefits/rewards/etc

Corvette Mastercard - Opened in February 2003. 3500 limit. 12.79 variable APR. No benefits/rewards/etc.

GM Card - Opened February 2003. 4000 limit, 13.49 APR. 5% earnings towards new GM vehicle.

Bank of America Platinum - Opened March 2003. 5800 limit. 10.99 APR. No benefits.

Best Buy Card - bought a computer at 0APR for 24 months - will not be using unless more specials like that come up. The APR is outragous, over 20%

NEWLY OPENED - Amex Blue Cash - 5000 limit. (Not sure on the APR yet, just got approved the other day)

I really wanted an Amex blue, and now that I have it, I'm thinking I should close the Chase and Capital One... but they are my oldest tradelines so I'm leary in doing that. My credit goals are met at this time. The only thing I want to do (and this will be in the next 2 years) is buy a house. I will not be seeking future credit.

I really like the benefits/rewards features, of my cards. I also want less cards, but with bigger limits... I don't like these small cards with high APRs and smaller limits.

I suppose if I don't go for new credit, then the ding I'll take closing my old accounts won't really effect me over time.....so... any thoughts?

If you made it through this post, I am amazed! Thanks in advance,
