1. Give it time. It'll get into a block sooner or later - probably sooner
I crafted the transaction manually with 0 fee (which isn't possible with the bitcoin client afaik) so I wasn't sure if it would ever be accepted.
2. You pass along and verify txs, as I recall. Frontline filters, keeping most of the cruft from the miners.
Okay, so you're stopping a flood of the network with invalid transactions, but you're not actually speeding up the rate at which any transaction might be placed into a valid block? This is kind of what I thought.
