Pugging ToC10/25 for some gear certainly isn't a bad idea.
Especially if you can get a hold of two relics or whatever they're called so you can get ilevel 245 T9 (Or even better, get in a full clear ToGC25 and get 258 T9)
I'd advise getting T9 legs and gloves at ilevel 245 and helm/chest/shoulders T10.
T10 chest should be your priority, not only is 2pcT10 very good but the T10 chest also doesn't have hit and it has ArP.
T10 shoulders is also a piece without hit, or otherwise the 245 emblem shoulders are a good alternative without hit and with ArP.
Banner of Victory from ToC5 normal is another thing you want to try and get until you're lucky enough to pick up the whispering skull, sharpened scale, DWB or Death's Choice/Verdict.
I would also consider not showing off the nerubian penishelm
