The cable for my Tiagra FD is too short and I need to replace with longer one, would appreciate some help and pointers to do it, do I need to disassemble the shifter in order to wire the new cable in and how about the outer sleeve thing? Thanks for any help.

Take the cable off the FD. Now install it from scratch as per Park Tool Repair:

When you have it properly trimmed and are ready for the cable - a new one wouldn't hurt - you want to pull the cable taut - not too tight, taut. Then apply 48 to 60 inch-pounds to the pinch-bolt. Then put it through it's paces.

It's always easier and faster to install a FD from square-one, than it is to make adjustments with it already attached. This tends to fix one thing - while throwing another out of kilter. Start fresh. You'll get it.

Adding an inline barrel-adjuster can solve many problems with the cable coming loose - or being too tight.

+1 on the barrel adjusters. The only way you can really dial in your shifters is on the bike, on the road. Barrel adjusters can give you that little tweak you may need and you can do it while in the seat.
