Hrmm some interesting choices with that suit build.
The only way you could get skills off the belt slot/ cloak slot would be if you have focus (obi di ense) / archery (despicable/unforgiven). I don't think there are any +skill gorgets.
You could buy a legendary piece of jewelry with more + skills on it (in addition to the hci dci etc), thereby freeing up skill points. Those can run into the several hundred million mark though.
You do know though that you will NOT be able to use weapon specials right? You need 90 REAL skill in tactics and weapon skill to use them. Wouldn't it normally be a better choice to have +skills for one of you other skills? If your not using tactics for the weapon skills it seems weird to have it on the temp.
From stratics "Warriors who have reached Expert (70) skill level in their weapon skill will be able to execute a weapon's primary special move. Once he or she has reached Master (90) status in a weapon, the fighter may execute the secondary special move while wielding weapons of that skill — making them twice as deadly! The skill level required can not be achieved through use of skill enhancing items, such as rings and bracelets, only real skill points are taken into account."
Alternatively you could use jewels with ssi, + ranger's cloak+ cameo +animated legs and get like 40 ssi without even considering the wep or most of the suit. There is garg stuff as well (which it seems like your character isn't). This way you could use a Captain John's hat, mark of travesty etc, for a lot of those points you need.
