Tubelab SE choke, run cap, and R6 resister questions.

Hello all I'm trying to finish my TSE build that multiple moves and other real life stuff interrupted. It is the original TSE board which has been populated for a couple of years waiting to be put in a chassis and wired up. It has been set up for 45 tubes.
I have a few simple questions that will help me finish this project.
1-Does the choke get wired directly to R4 pads?
2- Do I need to change C4 if i add the choke? it is currently 47uf 450v and my transformer is 540ct
3-Are there pads to connect the external run cap? I'm a little fuzzy as to where to connect it to the board.
4-and finally while going over the assembly manual I read that R6 was changed to a 6.5w resister, I have a 5w one in my board. I plan to replace it but I am having trouble finding a 6.5w can I use a 7w without causing issues?

here are some pics of my board and its soon to be new home. The chassis was my first attempt at veneer so its not perfect. Top plate is 1/8in aluminum which I plan to polish.
