Hi ricky,
in this scenario, i beilive u want to have 2 diffrent physical connections for redundancy and load sharing. in this case, on gig link you can increase the port cost >19 of 1st vlan so that it goes from Fastethernet port and on Fastethernet link, you lower down the port cost <19 of same vlan so that this will go from Fa link.
By default cisco switches run PVST (per vlan STP). this is fine for your network. kindly update me if you need any further asisstsnace here.
