What type of engine should i expect to find on free webhost?
Generally, myisam is a given, and in some of the decent free hosts, you can find innodb.
I've almost never seen a free host offer something other than those two by default.

That depends on what you want to do. If you want transactions, you'll want to have innodb. Transactions are really rather powerful and nice, and can help avoid the need for DB locking.
But if all you want is update and select, you don't need to worry much.
