Aveyfan, most likely you'll go to the summit from Kredarica, maybe from Planika. You can get there without issues from Krma or Pokljuka. Path from Kredarica to summit is steep indeed but also excellently protected. Most of the time you can clip in and hold pegs, cables and solid rock. Path from Planika meets the one from Kredarica about a third up and is quite "loose", I don't like going from Planika myself although the path is nice and avoids crowds. For me the section from Mali to Veliki Triglav was psychologically most demanding first time, although practically horizontal, but requires good focus.
Maybe another tip:
I think it'd be useful to use spring days for some safe "cabled" tour, say Gradiška tour or from Tacen through climbing kindergarten to Šmarna gora (Grmada). Here you get somewhat similar conditions and gather almost all needed mileage (balance, technique, psyche), or find out it might not be for you yet.
Look at the rock, not the drop, do what's needed and don't think what could happen to you.
Make a two-day tour, do the summit ascent midweek as crowds can be an issue since you spend a lot of time figuring how to pass, though it's doable. I'd suggest ascent to Kredarica Sunday afternoon, summit Monday morning when rested, and enough freshness left for descent and back to valley.
Don't overload yourself, don't overdress, leave most stuff at Kredarica if your further plan allows.
And if due to weather or bad day you don't make it, no big deal. Everything will wait till next time.
Good luck.
