Logical Shift Left (LSL) shifts the bits in R1 by a shift value. In this case, the immediate value 3, and drops the most significant bits. Nettetsal (or its synonym shl) left shifts (multiplies) a byte, word, or long value for a count specified by an immediate value and stores the product in that byte, word, or long respectively. The second variation left shifts by a count value specified in the CL register. The high-order bit is shifted into the carry flag; the low-order bit is set to 0.

The ENTER instruction sets up a stack frame by first pushing EBP onto the stack and then copies ESP into EBP, so LEAVE has to do the opposite, i.e. copy EBP to ESP and then restore the old EBP from the stack.
