Should I import to bitcoin-qt and delete unconfirmed tx's?
should I wait and see what gets confirmed?
Whats the best way to go around this so that the coin is spendable by someone and not stay in limbo forever?
I'm not sure, but the first transaction you posted cannot be found at blockchain.info https://blockchain.info/search?search=23be7665094e1829fa2a5f79b5076075c3efbba78215fd886d3eb930261c2afe
Second transaction indeed shows a double spend.

My gut says you should wait a little bit.
