Hi again rachgo729,
If you want to stay in the mountains, then go straight to Mürren. Interlaken is more like a gateway to the region: easy train connections, lots of shops, but it's not in the mountains, nor is there a lot to see in the town itself (check the link I gave you before). I would not recommend Gimmelwald. It's not more than a few houses. A beautiful place, but not very convenient.
Don't count on doing the Eiger Trail in May. It probably won't be accessible because of snow. It opens in mid June on average. Trails below 2000 m should be accessible, but you won't know for sure until you're there. Please find suggestions on the Interlaken page.
A Swiss Transfer Ticket Combi might be the best rail pass for you. In that case you only need a ticket from Paris to Basel as the rest is covered by that pass.
