Hi All!
I hate to be opposing council on this one but I recommend not apping for anything till December period. You just got in with 3 new cards, all with lower limits, and one of the new cards is Barclays. I'm thinking, if you app for anything in Dec, app the Amex revolver you want then the Wally World card. Your scores will be near approval rating with Amex for the revolver then so I give it a pretty good chance. Probably be another 1-2K limit but Amex is awesome with SP CLIs and will grow with you to the limits you are looking for in a card. After gardening your Amex to the limits you are comfortable with, then app the Citi and Chase cards. They love matching other creditors limits. Credit is a patience game and you should plan out your attack to getting where you want to be over time. It doesn't always happen over night. 
Don't stay stuck in low limit land. Apping a bunch more cards now or the near future will only get you that. JMHO
Just re-read your original post: adjusted apping opinion strategy
Starting Score: 642
I would close the orchard, cap one, HSBC. Personally Wally card right now is fine. But I wouldnt App for anything else until jan 2013. In jan 2013, I would go for Amex revolver. Don't worry about your exsiting limits. Just use the zync to build up internal limit on it and you will be fine. Also, jan 2013 will give you max backdating. I still regret having December open date on my Amex plat. If you don't get Amex in jan, then app for the other cards as no harm from Amex app as it will be soft pull. If you get Amex, might want to wait till 61 day cli to see what limit you have and let it report before apping for other cards.

I agree about the apping in Jan instead of Dec. Optimize backdating! Otherwise, I stick to my advice.
ok, just wanted to update you guys. i did FINALLY decide to go ahead and app for the wally card and boy am i glad i did. GE not only instantly approved me but gave me my HIGHEST revolving CL to date!!!! $1500. im really happy right now and think i made a step in the right direction. maybe from here on out ill be getting more than just the toy limits ive been getting. i really want to thank all of you for your advice, wether you thought i should or should not apply for the card, THANK YOU!!!!! i will be following your guys advice on app"ing for the BCE next year and hopefully AMEX and their CLI policy will help boost me to 5k plus limits to get out of "toy limit land" lol THANKS AGAIN, you guys are AWESOME!!!
(guess i have to drop my spade now and start the garden again lol)
You just better hope barclays doesn't catch wind of it. 
They tend to get a little upset when they find out you're cheating on them haha.

Lmao thats Hilarious! hopefully since my util is down to 7% and barclays is still getting decent usage they'll leave me alone......i hope
That is a nice walmart limit. Have fun waiting for the card, it's terrible
I sat at my mail box every day because all I wanted to do was activate it for my free TU08 turned out to be the exact same score as my CK.
