Your stock t-bar can work, you don't need a new one, if you're trying to save up for a 3" lift (A-Arms, etc...)
The winch may drop the front a smidgen, but the t-bar limiting lift factor is where you hit on the way up...you can only adjust up so far before you lose all uptravel...so around 1.5" is about it.
Adding the extra weight upfront just means a little more tension on the bar at the same ride height.
A better bar might ride better.
