Restoring a WordPress site from WAMP with only .ibd and .frm files, into a new WAMP with ... .myd and .myi files?
.myd and .myi files are the data and index files for MyISAM database engines. There is nothing wrong with them being there. They won't affect in any way your Innodb files that you are copying. They don't have to be overwritten if you copy the files into the folder.

In my installation of wampserver the MyISAM files (myd and myi) are one folder deeper than the ibdata1 file. That folder name should be the name of your database. If its not there then create the folder with the database name. 

Copy the data that you have over. This probably won't worth without ibdata, but just in case, after copying the other files into the appropriately named folder, click the wamp icon in the bottom right of the screen and select my.ini. Add the line:

innodb_force_recovery = 1


Restart wamp server. Let me know if your database is able to actually get anything out of the files you copied over.
