Yeah nice knight! Good choice of red.
In regards to starting 40k, decide what you want out of it first. Official GW shops are deluded, and the internet is full of annoying people with regards to balance.
An independent store is a good start, state what you want from the hobby.
It's a lot of fun but you need to find the right group of people.
Also prices are cheaper online, element-games is good for example, if you don't have an independent store.
Vallejo paints, Army-Painter spray, and whatever brush floats yer boat.
