Clueless. Need Help/Suggestion!

Hello everyone, Just need a bit of guidance on what to get.. basically i bought a specialized Hard rock bike half a year ago.. everything was perfect until.. yet again... a ******* stole the front wheel (At least not the whole bike like last time). So, now that im trying to to repair it and get into cycling again, i been looking around ebay and buying what i need, so far i got: 2x Schwalbe City Jet's 26'' x 1.95 ( Are this ok? Mainly for fast cycling in the city.) Got 2 so it would match the back wheel <_<.. i think they are an upgrade anyways. 2x Slime inner tubes (Presta) And now where i have no idea is on which rimms to get? :/ i dont want to spend to much money, so really dont mind second hand on ebay. (The rim i have in the back are alexrims specialized, should i keep those or replace?) So my main question is, do you guys have any suggestions as to which rim/ms to get? & Anything else i will have to also buy in order to finally be able to ride my bike again? Thanks a lot for your time and help guys! really appreciate it! Oscar
