Thanks to both of you for your replies.  Yes, this is just for 1 player battling.  Right now I never use items 4-7, they just fill empty spots.  My goal is to be able to do decently if there is ever another plot or war where there is fighting.
 
Aquamentis12, I can't even imagine 5 reds.  I will probably stop training once I hit the maximum strength / defence multiplier level, and then just sit there for a while, spend my money on weapons instead of codestones.
 
I am considering going with the Bag of Healing Dust, depending on what else I decide on.  Otherwise, I will definitely pick up the Velms Healing Potion.  More healing for less money is a good deal.  I could still redeem my obelisk points for the Rejuvenating jar of brains, I have enough for 6, and then sell them to subsidize my other purchases.  
 
It sounds like Downsize would be a good, affordable addition, I can add that for sure.
 
Hubrid Nox Memorial Shield is a definite possibility.
 
Would it be worthwhile to upgrade the DSPBB to a Kelpbeards trident?
 
One thing I'm finding hard is that some of these things have no prices in the Trading posts, so it's hard to get a feel for what fair pricing is.
