Not so good on early streets, raise on 5th

[MarkGritter]

I think I should have folded this hand on 3rd; would you guys 'defend' here or not? This is Party 1/2. Comments on all streets welcome.

On 5th I felt like I had a golden opportunity to knock out two better high hands and try to survive against the low. Good? Bad? Pot too small?

Checking 6th: I assumed I was up against a made low or a high with very good draws to beat me or make a low.

7th: I value bet after hitting my donk full house. Rest of action not shown... Because there was no bet on 6th, my read was that I wasn't actually up against a low. Would it have been better to try to induce a bet here from a worse high?

I was very confused about my opponent's holdings throughout the hand.
