First things first, what theme do you want? There are mainly four big Skaven clans and all have different personalities and units. Skryre have the most advanced technologies, for example the Jezzails, doomwheels and ratling guns. Eshin is a bunch of assassin, the nightrunners. Pestilence is like founders of diseases and such, they have the Plauge monks. Last but not least Clan Moulder mutates foul beasts like Rat ogres. It's smart to only buy units that fit your strategy. Please remember though that the army you're into is one of the most numerous armies in the warhammer world. Skaven players got hundreds of clanrats and slaves at their disposal. You have to paint and invest in lots of models. Well of course everything depends on how many points the army's worth. A 2000 pts army is pretty decent for a long and fun game and you'll not have to buy massive amounts of clanrats. Clanrats is in fact the core unit in your army, so even if this guy have offered you his stuff, it's not very wise to buy everything.
I would recommend buying the Island of Blood starter set, because basically you get a really good base army to expand and the rule book. If you however don't have the need of rules or just don't want the extra High Elves you can buy a battalion boxed set. Anyway you should at least get one of them to start with.
I would do it like this. If you buy Island of Blood then you can buy any of these: 3 Handlers and 2 Rat ogres. 9 Jezzails. Box Stormvermin. 1 or 2 Ratling Guns. And ONE Doomwheel. You army is now based on Skryre and Moulder, you will have both crazy shooty stuff and grotesque monsters. From here you can buy pretty much anything you want, BUT stick with your theme, that's very important or else you'll have a little bit of everything and in most situations that won't work. If you buy a battalion it already consists of some Plague monks, 40 clanrats, two rat ogres and six giant rats. Build the army around a Moulder/Pestilence theme. That means you have the opportunity to get for example: 20 more Plague monks so the number increases. Again the 3 Handlers, 2 Rat ogres. A grey seer unless you choose the one on a screaming bell. Perhaps the stormvermin, only if your planning to have less clanrats. Screaming bell if you don't take the standalone seer.
Well I hope this will help get a bit more insight on what you should do. If your not sure, choose the models you think look most awesome and always stick with your theme. Remember to buy the Skaven army book. From there you can calculate the unit costs for all models and design your own army. I wish you good luck.
