5dimes is widely regarded as the best book for US players. You could check out Bodog and TheGreek as well.
Yeah, that's the bank blocking it on your end. Direct deposits via credit/debit haven't worked in almost a decade. The previous workarounds involving a 3rd party such as FirePay or Neteller are also no longer options for US players. There used to be another workaround, where you could buy prepaid giftcards at places like Walgreens and such, but even those block "gaming" transactions now. Buying in on credit/debit is almost impossible now. You have to wire it in or do WU.
