Morning 
Welcome to paintball! I would just like to build on what Rat said.
Goggles are important and the first and foremost, get yourself a decent pair of second hand goggles off here like i3 pros, e-vents, v-force grillz or anything else with a thermal lense that will not fog up, you can pick these up for aroun £35ish from here, just ask for clear pics if you want anything clarifying and check their feedback threads in the approved traders section. The two that I saw in those packages are not thermal lenses and look rather uncomfortable.
Again, you can spend about £30ish on a good hopper on here in the fore sale part which isn't gravity fed, this will save you loads of hassle out in the field, its not much to spend, and will save you having to shake the loader whenever you actually need to shoot someone.
Air tank - Covered as post #9
Marker - Well, if you want to take this up as a real pastime, get something abit more... fullproof. both markers in those packages will do you for now, but in about 2-3months time down the line you will kind of regret having something which isn't all that special from a site marker. Spend about £250 on either an electronic marker like that one mentioned in post #7, or if you want to get more scenario based get a tippman or a bt - you will have to ask others more about mods etc for these.
Knee pads - you might not of thought of this but I think knee pads are highly essential, you never know where your knees are always going the wrong end of a stick or a rock can really hurt! just a consideration - best to buy new, I know they don't look cheap but there always worth what they ask for.
Don't skimp if you have the cash, you might end up kicking yourself once you spend money on not such great gear... I know.
Best of luck!
