I am strongly against hiking in runners, be it mountains or beach. Main reason being ankle support. You can twist ankle crossing boulders, hit rock etc. If you are getting blisters in your hiking boots, it is because they don't fit well. Good, properly fitting hiking boots can be more comfortable than runners! For beach hike I'd also bring Keen sandals; this is for walking in surf, around camp etc. They can be tied easily at the back of your pack & are not problem to carry.
Tarp is good idea because if it rains too much you will need that shelter in the evening to dry off, cook food etc. Rain pants if you don't have them, standard fast drying hiking pants should be ok. Then simply change into dry pair of something your brought along for around the camp while these are drying off (under the tarp). Just don't wear cotton.
