Confirming travel costs for hiking around Murren
 

I am staying in Murren for 5 nights. Below are the hikes/activities I am planning on doing from there. I have obtained the travel costs of getting to and from these activities (funiculars etc) from the SBB website (Price with no rail pass discounts):

-Schilthorn: CHF 82.60
-Murren to Gimmelwald (walk down, transport up): CHF 6.00
-Männlichen-Kleine Scheidegg Trail: CHF 83.00
-North Face Trail: No transport required from Murren
-First to Schynige Platte* trail: CHF ~87.00
*SBB unable to show cost of return trip

Questions
-Do my travel costs look about right or am I way off?
-Would it make sense for me to buy the Swiss Half Fare card? By my calculations, the total cost for the above is 250.6 CHF, or 125.3 CHF with the Swiss Half Fare Card, which costs 120 CHF to purchase.
-Can I use both the Swiss Half Fare Card and the Saver Day Pass together to travel around Switzerland?
