Brewing First Partial Mash, need input on hop schedule

[novaau]

[Sorry, off topic]I completed my porter without much trouble, and it is fermenting. Anyone know what the stuff floating in the krausen is?[/Sorry, off topic]

If I am going to brew this Sunday, I figure I need to smack my yeast and make a starter Thursday or Friday night, give it a good 18 hours or so on the plate, fridge Saturday night, take out and put on plate Sunday morning?

I have also come up with a new schedule, based largely on the input received here (thanks again!):

FW: 1.5oz Ahtanum, 1oz Styrian Goldings
30min: 1.0 oz Ahtanum
20min: 0.5oz Hallertauer
15min: 0.75oz Ahtanum
5min: 1.0 oz Saaz
dry hop: 0.5oz Sorachi Ace

Beer Calculus is saying 61.7 IBUs.

My starter is going, but I need to add volume (I had a couple of boilovers when preparing my starter wort), to get it to 2L or a little more. I figured the best procedure would be slow down the plate, take refrac reading, add cooled wort to get to 1.040 brix equiv, spin until ready to pitch (18-36 hrs later). Any suggestions?
