As far as the size goes, it's pretty much different among the different manufacturers. Usually it's aout 1 size lower than your normal shoe size - but again - different manufacturers have different sizing norms. A "RollerBlade" size 10 might not be the same as a "CCM" size 10.
You then have to decide what kind of skates you want - fitness, leisure, extreme, hockey, etc.
It all depends what you want to do with the skates. The diffrent genres are made of different materials/methids of construction, and the WHEELS are different. If you're starting out but want to eventually do some serious skating, stunts, and other fun things I suggest you go with a harder boot. The fitness and leisure skates will have a softer boot, that, while being more comfortable, has less lateral support and rigidity necessary in tight turns and stunt manoevers. Laces offer the most control of pressure points around the foot - you can make it tight where you want, and looser where you need. However laces are usually reserved for the extreme "stunt" skates and hockey skates.
The other major factor is the wheels and the bearings. THe higher the number of the bearings (ABEC 5,6,7 etc), the easier the wheels will turn (less effort required to spin the wheels) and the faster you will go. Also, the bigger the wheels are (78-82mm are "big") the faster you will go in a straight line and the less effort is required to go a given distance. For leisure and fitness skating the wheels are usually big with bearings with a high ABEC rating. For stunt and hockey skating, however (where you want to stop, go, and make tight turns continuously), smaller wheels (72-76mm) and lower ABEC-rating bearings (3,4) are the norm.
The one other thing to consider is the wheel composition or "hardness". High numbers (82A and above) are harder wheels that will take more abuse, last longer, but have less grip. Softer compound wheels (72A) have more grip, but will wear out much faster and will break under extreme use (sliding sideways, sliding along rails, etc).
Disclaimer: technology continuously evolves with these items, so while all of the above holds true for a few years ago when I was more actively involved in the sport, I don't know what changes have been made in the past few years.
Hope this helps! Have fun.
