With bitcoin, I'd use the JSON-RPC and keep track of transactions in blocks and have to build the UTXO database myself. Is it the same with ethereum?

There is no such thing as UTXOs with Ethereum, it's account based instead. You can query a nodes JSON-RPC to get balances, code, storage, etc. There are also many libraries (including Web3.js) to make this much easier.

  • I can query ANY account balance directly, regardless of whether or not I have the private keys?

  • Correct. You do not need an accounts private key to query balances.

Ethereum is not depended upon the unspent transaction output or UTXo. Instead, it depends on the state of the system. It only has account address linked with balance. For spending a certain amount, we only required an account with a balance greater than the amount to spend and its passphrase.[spending with wallet]
