Grain bill looks good. However with a projected final gravity of 1.031 it's gonna be sweet. Might want to cut the maltose in half or toss it totally, try to bring it down toward 1.025 would be my goal. If you do that might be a good idea to bring the OG down to 1.090 range. Just thoughts.
I'd simplify the hop schedule to a single 60 min addition. I like your bill, but any noble hop subtlety is gonna be lost in this monstrous spiced brew.
I'm no expert on the spicing end, but would add the boil spices at 2-5 minutes. 10 oz of rum is going to be overpowering. I'd look at more like half that, 3/4 if you wanna push it.
Overall looks good, just tweak a bit.
