If I want to verify a transaction by checking the validity of an input transaction, is there a way of finding the block containing the transaction, without having indexed the entire blockchain?

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

If you have an internet access you can ask blockexplorer/coinbase/blockchain.info
If not, no. Sadly
