Don't be frightened of verbs anna7. Admittedly people get hung up on them because you can't form a sentence without them, but if you learn the rules then it might be easier than scrabbling about and forgetting. You say you are ok with the present and past, so that's really good already. For future and conditional make sure you know the infinitives, and just add the avoir bits for the future . As someone suggested, start with common verbs you learnt at school like manger to give je manger*ai*, or finir to give je finir*ai*, vendre to give je vendr*ai*. Then tackle the irregular tricky ones like faire to give je fer*ai*, aller to give j'ir*ai*, voir to give je verr*ai*. Notice that because you already know about the avoir endings, half the future tense job is done already and you only now have to bother about the beginning part of the word. Je serai (être) and j'aurai (avoir) are vitally important and concentration is needed for the modal verbs, especially devoir.
The Conditional is similar just slap on the imperfect endings ais je mangerais etc.
Some people find it boring and tiresome because they just sit down to learn tables of verbs, followed by worksheets. Once I think I know the rules, I prefer to get up and talk to the dog saying, "demain j'irai aux magasins et j'acheterai ..... après tu ferras ton promenade, le facteur viendra avec les paquets et nous mangerons à midi. And so on making a little scenario. Make it meaningful to you. Otherwise pin a list by the loo and go through it several times a day!
