Need recommendation for parts upgrade
I have 2009 Fuji Crosstown 4.0 bike. I wanted to sell it and buy a better bike but can't find a buyer so I have decided to upgrade it instead. The upgrade path would probably cost more but I do like this bike's geometry so it may be worth to put some money into it. To give you a small overview, I am 6'4", 200lbs and I do only recreational riding on a flat paved surfaces.
Here are the parts that I would like to replace:
1. Wheels definitely need to go. The current one are generic Weinmann alloy wheels that bend too easily.
2. I would also like to replace the rear derailleur as I have the plastic Sunrace RDM4S 7spd there now.
3. Finally, I would like to get better brakes. The current ones are ProMax Forged alloy, linear pull and I just simply do not like this type of brake. If possible, I would like to upgrade to the "inverted" V-shape brake (not sure what's the proper term for those, A-shaped?).
So what are your recommendations? I am not looking to spend a lot of money so looking for good budget buys that will outperform the gear I currently have. I have enough skills to get all the parts replaced myself. I will just get the bike properly tuned after that at the LBS.
Here are full specs on the bike:
