Another Credit Card Help Thread

I just purchased a house in Central and want to get a system down to start gaining rewards for all my purchases.
I would like to develop a system where I am using two credit cards. One for everyday(cash back) and a card for recurring payments such as bills and subscriptions(travel). I am trying to find the best cards for the job. Just trying to use these instead of no rewards debit purchases. Also, we don't travel and use hotels that often.

Spending:
350 month groceries
20-250 month gas
100-200 anything else
~500 bills, recurring

Everyday:
AMEX Blue cash preferred
6% supermarkets
3% gas
1% everything
75 annual

Discover IT
5% revolving
1% everything
0 annual

Chase Freedom
5% revolving
1% everything
0 annual

Any other choices?

Recurring:
AMEX Blue Sky
startup of 30K points ($400)
1.33 points everything
0 annual

Cap One Venture
2x points
59 annual

any other choices?

My concerns are:
- We shop at Sams club every so often and they don't take AMEX
- Walmart and Target style stores don't get 6% back on AMEX
- Blue Sky has higher bonus plus 0 annual which is nice initially and instantly having $400
- Venture is a better by 50 dollars a year with the 59 annual


Any other system would be greatly appreciated. I have an excellent credit score so I can apply to all of these.

PS: I've also looked into the PenFed gas card but I don't know if I want to keep up with a third card and constantly remember to use it. Though I only really have to remember to ACTUALLY use two cards since the travel card is only with recurring payments.

edit: I am also a member of a discount club that gives me a % back on most stores booked through them. This includes Best buy, Home Depot and pretty much every store imaginable. I would like to combine my % back from the card and this membership to reap maximum benefits.
