1. I'm gonna say no to this one just to make it easier for mods to skim for rolling problems.
2. Yep, it doesn't cost anything to get an item from pickup so the pickup roll won't cost any energy even if it is an item.
3. Ah I answered this above xD Nope it won't cost energy.
4. No it's a separate roll from he 10 rolls you would normally get, the same as rolling a Trawl Orb would be counted separately. As such we ask that you make it clear which rolls are which by labelling them appropriately.
Hope this answers your questions!! And apologies if it takes me a bit to get around to your character, I'm somewhat busy this week but I'm aiming to take a look this weekend if no one else gets to it first. ^^
