My last character was level 30 and set up for stealth so she has all the perks like ninja, silent running and is a perfect character (10's for every special stat, 100 for skills etc). My main weapons are pretty well the same as yours, except she has the Chinese stealth armour and Jingwei's Shocksword to be the invincible/invisible ninja.
Checking my stats I've put 60 hours into this character and built up something like 30,000 caps and almost every unique weapon (except Callahan's magnum and the novasurge) with every quest completed for all 5 DLC's. After hitting level 30 though it gets to a point of being 'instant win' against anyone and anything....even more so when you have 400 stimpaks built up over all that time...
If you have any question's about the DLC's feel free to ask.
