2kg is too much? hmmm... sweetheart, you have no idea how strong you are! Just because we're women doesn't mean we're going to break and half picking up a barbell. ;) I'm 5'2 119 lbs; bench 90 lbs and deadlift 180 lbs.
You can start with adjustable dumbbells. That way you can continue to move up in weight as you become stronger. They're worth the investment. If you want an effective workout, you're going to need a weight that you reach muscle fatigue (you can't possibly do another rep in good form) in 6-10 reps and continue moving up in weight. So buying 5 lbs then 10 lbs then 15 lbs dumbbells etc. and eventually realizing you need even more weight and having to buy adjustable dumbbells is going to wind up costing you more in the long run. Cut straight to the chase, skip the 5 and 10 lbs weights, you don't need them. I still use mine for smaller muscles.
IMO, a home gym is not complete without a barbell and bench. If you strength train correctly, continue to move up in weight... you're going to quickly out grow dumbbells.
Personally, I don't pick up a weight any less than 40 lbs for my rows. I do compound exercises and use my husband's barbell and bench for most of my exercises; deadlifts, squats, lunges, overhead press, bench press. The heavier you lift, the faster you'll see results. Lifting light and high reps is very ineffective and will be a waste of your time. It's essentially cardio (and not one with a good calorie burn either) and it would take you eons to build any noticeable strength or muscle.

Take your focus off the Marshmallow. www.leangains.com/2010/01/marshmallo
"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. It doesn't happen, what does happen is you get results. Lifting Barbie weights does nothing but waste time.
