Best online resource for guiding LLC owners through navigating taxes?

I started my LLC earlier this year with two other owners/members. We've outsourced our bookkeeping but I'm not yet paying for a tax accountant to be on call 100% of the time. Therefore, can you suggest a best online resource to things we should be considering when it comes to taxes? For instance, what should I be putting on the company credit card vs not (i.e. a new phone, internet at home, etc.) - OR are those things I should continue to pay personally and then "write off" at the end of the year?

OR, another thing that has come up > are there other things we should be thinking of/tracking/handling a certain way so that our end-of-year filing is smoother? Thanks!
