You have 3 options to get to First.
From Wengen you can take the cable car to Mannlichen then a bus to Grindelwald and cable car to First, probably not a good option if you are pressed for time and walking to Schynige Platte.
2nd option is a train from Wengen to Kleine Scheidegg to Grindelwald and then cable car to First. This is the most scenic but not covered by the STP if you have one but you do get a discount.
3rd option is train from Wengen to Lauterbrunnen then to Grindelwald and cable car to First. Similar to the route you will take after coming down from SP, this will be covered by the Swiss Travel Pass.
It is a fairly long hike so you should be sure to reach SP before the last train leaves, about 6:20 PM i believe.
Also as you approach the last leg to SP it is well worth taking the Panaramaweg route as It is spectacular scenery with mountains on the left and the Interlaken lakes on the right and it only adds about 20-30 minutes.
