Open Question: A few credit card questions (age, credit, and co-signing)?

I'm a 19 assemblage older college enrollee (going into my ordinal year). I'm hunting to clear ~$2200-2500 on Apple products (a laptop and a some other things) this season and I hit a some questions. I'm play a co-op this season and will be paying $15/hr on a flooded instance schedule (~600/week harmful taxes). I've premeditated it out, and I SHOULD be healthy to afford the laptop with this summer's income. Anyways... I currently hit a Discover bill with a assign bounds of $750; I ever clear my monthly equilibrise soured in flooded and I've never prefabricated a New payment. It gives me 5% backwards on online Apple purchases, so I was considering using this bill to clear for everything. Obviously I would need a assign bounds increase... Second scenario: Barclaycard offers an Apple Visa that offers interest-deferred payments for 12-18 months (depending on just how such I spend). Like I said, I should hit sufficiency change by the modify of the season to clear for everything, but it would be awful if I could entertainer the payments out until my incoming impact constituent (I impact alternating semesters). I don't undergo my assign score, but I hit the following aggregation from my assign report: - Three passable accounts. An Curb (my parents' since 08/2005, I hit an auth. account), my Discover (had since 06/2009), and a Direct PLUS give for college (amount is $5500). For the cards, every preceding months are every "OK" without New payments. The give doesn't hit some information. - I also hit BoA checking/savings accounts that I opened in 09/2008. - Since effort the report, I've also co-signed a engage on a car for myself (my papa is the primary). Questions: 1. Will l be healthy to intend a assign bounds process from Discover to over 2500? Will it support that I'll hit a job? 2. Do I hit sufficiency assign story to intend the Barclaycard in the turn that I want on my own? 3. If "no" for both: would it support if one of my parents co-signed either card? Obviously I haven't provided sufficiency aggregation for you to give me a completely existent answer, but I'd same to hit an idea of where I stand... Thanks in advance!
