In order to use utaugrowl, you need to put it in the same folder as the resampler you want to use, then change the name of the file to the resampler + "_ug" at the end. So if you want to use TIPS, rename "utaugrowl.exe" to "TIPS_ug.exe" and set only your resampler (Tool2) to be TIPS_ug.exe.
Moresampler does indeed include its own harsh vocals flags. These are MC (coarseness), MG (growl), and MD (distortion). The default value is 0 and the maximum is 100. However, they don't really sound that good, so you're better off using utaugrowl, or vibrato growl, or dedicated growl samples recorded for the voicebank.
