My home is 90% electric, but my furnace is electric and gas, I am curious about how to change to an all electric furnace since my air conditioning and hot water tank are both electric. Will this require me to amp up my electrical panel?

Why change from a gas furnace to electric? In most areas, gas is much cheaper than electric when it comes to heating. However, if that is not the case in your area (and I would research that if it was me) you will need to put in a complete new electric furnace. You will have to have in an electrician to see if your current electrical panel will support the extra breakers and load.

Just out of curiousity, why are you replacing the furnace? Is it just shot, or is electricity really cheaper in your area than gas? I would suggest talking to at least three heating and cooling companys before I made the switch.

Well I figure since majority of house runs on electricity, I may as well switch my heat to electric also. Because it would be cheaper than natural gas, since I would just need it for half the year or so.
