I need some help/advice

So in two weeks I'm starting work from home and I got a gym membership. I found it hard to go in the past because I was commuting a LOT.

1. I've never been good with dieting/exercising/etc. Do I start with a lot of cardio and then work in weights at a later date?

2. Am I better off getting up early and doing a workout before I start working or after?

3. This is totally weird...but I find I sweat, but I guess not as much as I think I'm supposed to? I want to push myself, not hurt myself, but definitely get going.

My main goal, besides my health, is to lose some weight. I know it won't happen fast, but that has been the tough sport for me in the past. I've gone to the gym and not seen results then given up. I have 60 lbs I need to lose.
